Hi Mark,

i really think it could be an issue of naming... As if i boot from the 
install-cd the raid-drives are named md124 - md127 and /dev/md/livecd:1 - 
/dev/md/livecd:4.

I installed a kernel with genkernel and its corresponding initramfs, but after 
booting i get the same errors. starting the busybox shows the /dev/md3 but i 
cant mount it in any way.

regards, 

Jens

I can feel your pain :(  This may not help, but I thought I'd mention it
just because nothing else has helped so far.

I started having random keyboard issues right after the most recent xorg
update on my ~x86 and ~amd64 machines.

Maybe just once/day or so I'll hit a key and the auto-repeat function
starts repeating the keystroke ad infinitum until I hit Backspace.

This is not a lockup like your problem, but it was striking that this
random keyboard problem started right after the recent xorg update.
(Yes, I recompiled all the drivers after the upgrade.)

Since you are recompiling/reinstalling everything anyway, what about
masking the most recent xorg-server/xorg-driver updates so you can test
older versions?  You quad-core speed demon ;p
   

I'm going to add this to the "to try" list.  That sort of makes sense.
Most of the time it is a hard lock up.  It won't even let me ssh in from
my old rig or use the SysReq keys.  Sometimes tho, it acts like things
are still running but the GUI is locked up.  I didn't get to try to ssh
in then tho.  I know once I had a compile running and I could see the
hard drive light blinking as it compiled.  So something was working that
time at least.   One thing I did learn, if the lights on the keyboard
are blinking, it's locked up tight.  If they are not blinking, I can use
the SysReq keys to reboot.

I also thought about just booting Knoppix and seeing if it works.  Maybe
it is just some weird code that Konsole and Firefox have in common
somehow.  The only thing is, I'm sure they will use different version of
all the software.  It may not make any difference except to rule out
hardware.  I'm pretty sure hardware is OK but we know how hard those are
to track down.

One more thing on the try list if this doesn't work.

Thanks.

I'm stating the obvious here, but have you tried restoring from a back up that
you made before these problems started?

   


I usually have a backup but I got rid of it a month or so ago.  I was 
planning to take the drive out and use it for something else but never 
got around to it.  Before that I played with LVM a bit.


So far, I have upgraded gcc and glibc and the emerge -e world is almost 
finished.  If it still locks up, I'm going to try a different xorg and 
friends.  Someone else mentioned a bug that is pretty close to what I 
have going on.


I'm going to fix this even if I don't know for sure what caused it.  If 
after this emerge it works, it has to be either gcc or glibc.  If it 
still does it and I upgrade/downgrade xorg and friends then it works, 
then I know it was one of those.


I'm just hoping for a fix and glad I got Fluxbox on here.  Fluxbox ain't 
fancy but it works well for a backup..  I have to add, it is pretty 
snappy on a 4 core 3.2Ghz CPU with 16Gbs of ram too.  lol

That's a kernel panic. You can have the system reboot itself after a
panic by adding kernel.panic=N to /etc/sysctl.conf, where N is the number
of seconds to wait before rebooting.

Kewl !!!  I just saw that in the file but it is commented out.  Like this:

# When the kernel panics, automatically reboot in 3 seconds
#kernel.panic = 3

So, I uncomment this and the system will reboot in 3 seconds?  Does it 
sync and unmount or just do the same as me hitting the reset button?  
I'm going to uncomment this either way.  If it is locked up, does it 
matter if it is it or me that resets it?  lol


Is there a way to set this without rebooting?

Alan, while you got a eye open.  Can you try to do a search for all bugs 
related to konsole and glibc?  When I go to BGO's search and try to 
search for that on ALL bugs including closed ones, I never get anything 
but the "please stand by" screen or a blank screen.  It acts like it is 
searching but never returns anything.  I go here:


https://bugs.gentoo.org/query.cgi

Make sure you select ALL for the status.  I was wanting to see if there 
was any problems reported but fixed in some way.


I'm just curious if it is me or a website problem.

Omfg... Facepalm!!!

Totally ignorant i really did genkernel with initramfs, added dodmraid as 
parameter, ...

Should have simply done a genkernel --help, which showed up the "mdadm" 
parameter :-(

After doing this - and changing the mdadm.conf a litte bit - everything works 
as expected... Ok, not everything - should remove all the unneeded modules 
from kernel which i added to locate the error.

Thanx a lot to all,

The kernel is dead, it's all it can manage to reboot with it's last gasp.

You can set it with sysctl on the command line, or add it to the file and
reload the config with sysctl -p

> Thanks.  Why wouldn't that be a default I wonder?

Because it causes reboot loops if there's a basic error that causes a
panic when you boot.

You can also give it as a kernel option in GRUB, add "panic=N" to the
kernel options.

Taking a look at this bug today, is there any reason why the ebuild shouldn't 
simply RDEPEND="x11-libs/gtk+" (i.e. remove the explicit dep on gtk3), detect 
what version you have installed on your system and then either run 
--enable-gtk3 or --enable-gtk2 during src_configure(), depending upon which 
you're using?

ebuilds generally don't do this, because it is bad.  What you have and
what you want aren't necessarily the same thing.  Consider:

  * You don't yet have any gtk installed
  * You have gtk2 but actually *want* the gtk3 version, so you want
the ebuild to pull in gtk3 (or vice versa)
  * You have both gtk2 and gtk3 installed.
  * You have gtk installed, but don't want gtk support for a
particular package (if gtk support is optional for that
package).

easy.

Two USE flags: gtk2 and gtk3

in ebuild:

DEPEND="
gtk2? (x11-libs/gtk+:2)
gtk3? (x11-libs/gtk+:3)
"

in src-configure() write the code such that it establishes a 
precedence

If both flags are set, build against gtk+:3
If only one flag is set, build against that toolkit
If no flags are set, do something appropriate.

IIRC, it is frowned upon to have conditionals in DEPENDS based on USE 
flags so the above is best - take the small hit on disk space if both 
are set and gtk+:2 is used nowhere else (highly unlikely for quite a 
while still)

[gentoo-user] [OT encfs] When encfs gets hungup

[Harry Putnam]

Sorry about the OT, I couldn't raise a stir on the encfs group in
several days... I'm hoping someone here is experienced with encfs.

Actually I'm somewhat experienced with it myself.  I've been keeping
encfs directory for yrs now for special stuff.

Somehow I managed to really hurt the installation ... here is what I
remember having done:

Some how I got mixed up when running as root, and attempted to mount a
users encfs directory.  (Its a single user machine so it my users
directory) 

That should just fail with some kind of permission error since no one,
even root, can mess with someone elses' encfs directory.

But once I'd done that I could no longer even `ls' the subject
directory.  Not as user, not as root.  A simple `ls' would totally
hang the terminal.

Of course I tried to umount but really it never actually mounted.

I started getting this error: `Transport endpoint is not connected'

I could see roots attempt to mount the darn thing in ps wwaux output
and killed that pid.

Eventually (after posting several days ago on encfs list.  I resorted
to umounting /home (after full backup of course) and reformatted it.

I was then able to deleted encfs_raw and encfs_mnt.

But here is the real kicker.  Even after all that, and in fact another
full round of mostly the same stuff, including another reformat.  So
two reformats and two reboots.  Even with that, I still cannot create a
new enc_raw and enc_mount of the same name as the old one.

I would like to, because I have several scripts that depend on that
name.  Not a huge deal... but what could still be causing trouble?

I can create any number of encfs directories with different names.
Just not the original.

What happens if I try is that after creation (using old name) I can
move files to the new (with old name) directory.

But if I once umount it like: fusermount -u /my/oldencfs, then when I
try next to mount it, it hangs terminally.  Takes over the terminal
and kills all further progress (in that terminal).  This happens at
the point where I answer the passwd prompt with the appropriate
passwd.

(No .. no chance I'm entering it wrong... its been in daily use for
yrs).

I'm kind of stumped at what else to try.  I've used encfs -v (verbose)
mode and -f (foreground) mode but after entering the passwd... it
all just goes south... nothing more can happen.

Maybe encfs keeps data somewhere that I can delete and make this go
away?  But a `qlist encfs', listing all that got installed doesn't show
anything like that.

I've never used encfs, but maybe strace will show you if it's
accessing files anywhere else around the time it goes belly-up.

This is the way it was done for gtk vs. gtk2, but the bug has been updated 
since I first read it (over 24 hours ago) and apparently the Gnome team don't 
want the two separate flags in the future.

I'm not really a gtk or Gnome (or X11) user, so I don't really know, but the 
two separate flags did strike me as a bit of an ugly / clumsy way of doing 
things.

ebuilds generally don't do this, because it is bad.  What you have

   * You don't yet have any gtk installed
   * You have gtk2 but actually *want* the gtk3 version, so you
want the ebuild to pull in gtk3 (or vice versa)
   * You have both gtk2 and gtk3 installed.
   * You have gtk installed, but don't want gtk support for a
 particular package (if gtk support is optional for that
 package).


easy.

Two USE flags: gtk2 and gtk3

in ebuild:

DEPEND="
 gtk2? (x11-libs/gtk+:2)
 gtk3? (x11-libs/gtk+:3)
"


Actually, it's better to have "gtk2" and "gtk".  *Not* "gtk3".  That 
would repeat the problems of the past (gtk1->gtk2.)


But the devs have gone into ego-mode by now, so there's no chance in 
hell they would accept help or suggestions about this.  It has reached 
the point where accepting a suggestion would mean "losing the argument"

Highest version of gtk in tree is pulled in as a dep (subject to masking, ARCH, 
~ARCH, &c)

emerge -u1 x11-libs/gtk+  (assuming gtk3 is now stable)
or
emerge -1 =x11-libs/gtk+-3.0.10

(but gtk3 will probably be pulled in by Gnome3 (??) automatically when the user 
upgrades to that)

Compile against the higher one

This is when you should be using USE="-gtk", surely? Whether v2 &/or v3 of gtk 
is supported is irrelevant.

This is not entirely the case.  No one can enter an encfs mount
(destination) but the person that mounted it (by default), but anyone
can *mount* the encfs "source" (and thus become the owner of the mount).

That's probably why you got the above error.  But technically if you

If you totally remove the source and target directories, there is no
other information stored, which allows you to (e.g) encfs directory on a
vfat-formated USB stick and move it mount it on a different machine.
All that encfs knows about an encrypted directory is in *one* file on
the source directory (.encfs6.xml).  Once that file is gone, there is no
such thing as an encfs.

Having said that:
One of encfs's Achilles heel is its dependency on the boost C++ library
which is *very* sensitive wrt to API/ABI changes and the like.  It also
depends on OpenSSL which also shares this notoriety (although, in my
experience, less so).  So there is a possibility that an update to any
of those packages may have broken encfs and you need to rebuild the
package.

nsswitch.conf looks straighforward and should be default.  I get a lot

~/.ssh/config doesn't exist and /etc/ssh/ssh_config is all commented out.

If I remove the domain and nameserver declarations in /etc/resolv.conf
and add 'nameserver 8.8.8.8', it works properly.  Is this something I
should investigate, or more of a "don't worry about it" situation?  I
should be off of this wireless network very soon.

You mean like what they did with portage and python2/3?

Well, there was bugs in that (I reported 1 or 2 bugs myself).  It works
now (depending on your expectation of "works" but is very ugly.

They could do that.. I don't see it happening though.

I didn't want to comment on this thread (having been on both sides of
the fence).  But I will say this.  The best thing about Gentoo is it's a
"meta-distribution".  It gives you more control and more ease to do
things "your" way.  I think people should learn to take more advantage
of the latter.  I do.

Have you considered using PXE to network boot your systems? you can
have various configurations set up based on mac addresses to address
different hardware issues. I recommend trying out SystemRescueCD to
experiment with PXE booting for the client and server.

LOL Well I was up and running but now when trying to create VMs I get

dnsmasq installed. python-updater run. revdep-rebuild etc..

Are there any other GUIs to try for for virtualisation?

Or is it better sticking to CL to qemu-kvm?
Am I expecting too much for this just to work?

Yeah, I hope I don't offend Nikos by saying this, but I think he's allowing 
himself (from his comments in the bug report) to get way too bent out of shape 
over this, considering he could stick a copy of the patched ebuild in his local 
overlay and just compile against that until gtk3 looks OK under KDE.

I have to do this fairly regularly, because all the packages that are important 
to me seem to be completely unimportant to anyone else, and my bugs languish in 
bugzilla for months at a time.

You have to pick your battles, and (whilst I'm not always able to follow this 
advice myself) it's not worth letting some asshole on the internet have a 
negative affect on you.

Nikos has now spent *way* more time arguing his case in the bug report than he 
would have done maintaining the ebuild himself.

ok I might be being dumb but found a way round this (through trial and
error) 

In advanced options in step 5 of 5 select "Specify Shared Device Name"

Please note you'll need to create a bridge as well but selecting the
above removes error message.

Caw this is tough but fun.

I can honestly say that I haven't experienced so much pain working with
libvirt/virt-manger.  If I had I probably would have given up, but I've
been using it for years now.

What versions of packages are you using?  Are you mixing stable/unstable 
packages?

I can't really say.  I've never seen that error before.  What steps are
you taking to create the VM?

Ok, the problem appears that you never really solved the first issue you
had.  So that's causing other issues down the pipe, which is often the
case.

Using latest stable versions of all packages regarding
virt-manager/libvirt and all associated but I am using 
.39-r2 kernel (which oddly cures a usb issue I have been having
with .38 

There is post on the forum regarding this issue as well (recent)
but looks like no fix was found.

Have tried a few vms now and seen to be running ok. Was trying to see
any differences with VirtualBox (better speed/usability).

Can't say there is much in it but only a home user so will not see too
much speed difference anyway.

Using gui to create images on hard disc and running isos from there.

I perhaps should read the documentation but like to try things first
before getting too involved. lxc next!!!


Thanks for your guidance. I don't think I would have got this far
without it.

When I do ssh google.com the process hangs until I kill it, but it does
find the right IP address.  Along the way it checks /etc/gai.conf, which
is installed by glibc and is used by the getaddrinfo(3) system call.

My gai.conf has only three uncommented lines:

scopev4 :::169.254.0.0/112  2
scopev4 :::127.0.0.0/1042
scopev4 :::0.0.0.0/96   14

Of course, lots of other files are consulted, as already mentioned in
this thread.  I mention gai.conf only because I'd never heard of it
until I ran strace on ssh just now.

Admittedly there isn't much difference, so if what you are using works
for you why not stick with it. I still prefer encfs, although I have
admittedly never tried ecryptfs, for the following reasons:

  * It's FUSE, completely userspace and requires no kernel support
(other than FUSE) and no special privileges to mount (other than
fusermount).
  * You can have multiple layers of encryption on on source
directory.  E.g. two different passwords can give you two
different views of the filesystem.
  * In the documentation at least, it says when you upgrade ecryptfs
you should first copy the files from the old ecryptfs to an
unencrypted filesystem, and then copy it to the new ecryptfs.
That seems like something some people won't want to do.

There was a fairly well documented problem, on the Gentoo fora at least, with
the nvidia drivers, Xorg-server-1.10, KDE 4.6 and Konsole. I had it on several
machines that locked up as soon as you resized konsole. The solution was to
fall-back to Xorg 1.9 server and drivers. However, with the latest Xorg
drivers and nvidia drivers, the problem is solved:

[I] x11-base/xorg-drivers (1.11@01/07/11): Meta package containing deps on all
xorg drivers
[I] x11-base/xorg-server (1.10.2@25/06/11): X.Org X servers
[I] x11-drivers/nvidia-drivers (275.09.07@25/06/11): NVIDIA X11 driver and GLX
libraries

I am running kernel 2.6.39-r2 but i don't believe that is critical.

This appears to have fixed the problem with me opening Konsole.  I went 
back to 1.9 series and all is well with Konsole at least.  Now to figure 
out Firefox.

Re: [gentoo-user] Re: Firefox and kernel panics.

[Dale]

OK.  Back to the original thread.

Here we go again.  Everything seems to work EXCEPT Firefox.  When I log 
into KDE, I can run Seamonkey, Kpat, Konqueror, Konsole, gkrellm and 
such but as soon as I start Firefox, it locks up tight.  Tight enough 
that the kernel panics and it resets since Neil informed me how to set 
that up.  Thanks Neil!


On Firefox, I have unmerged both nspluginwrapper & adobe-flash.  Still 
does the same.  I also tried the unstable version of Firefox 3 and even 
the unstable Firefox 4.  I don't think it is Firefox itself but 
something that Firefox accesses or loads up.  Keep in mind, when I 
upgraded Firefox it also pulled in new xulrunner packages as well.  Is 
there anything else I should unmerge?  Keep in mind, I can't open 
Firefox.  Should I try to run Firefox as root to see if it locks up then 
too?


So, what in the world is it that Firefox does that can cause a kernel 
panic?  Also, I can surf with both Seamonkey and Konqueror and 
everything works just fine.  It seems only Firefox, any version, is 
affected by this.


Now what?  I use Firefox to go to youtube and stuff to get music 
videos.  It just does better than Seamonkey for me.

Thank you for your answers,

As you recommended, I visited www.openprintin.org/printers there is my
printer: Lexmark X5650 (fax, copier, scanner and printer)

Also, lexmark support website, claim there is a driver for Debian users and
RPM (32 bits only)

You can check it here:
http://support.lexmark.com/index?segment=SUPPORT&userlocale=EN_US&locale=en&productCode=LEXMARK_X5650&page=product&frompage=null

As you can see there is a 32 bits driver, I'm on a gentoo box using: ~AMD64

So, I downloaded Debian 32 bits driver (.sh) and I tried to Run, by a minute
I thought it was fine, but when it's about to finish, it shows me an error,
so this mean there is something wrong, I can't use this driver, besides,
rpm, does not work to, it just run splash screen.

Is there anyway to convert RPM or (.sh) to .TAR.GZ with depencys of course.

*This printer does not have wireless


P.S. If this printer works in Debian, Fedora, OpenSuse, why will not work in
Gentoo (best distribution for me)

You should continue to investigate the glibc thing. There was a thread
about how it's causing problems for someone running LibreOffice I
think.

You might also look more at what part of Firefox s causing the lockup.
Is it Firefox proper, or is it something caused by your homepage? For
instance, if they make use of Flash or Java it could be one of them
causing the lockup and not specifically Firefox itself. Can yo erase
Firefox preferences so that it opes to a blank page. Does it still
lock up. Have you removed all cookies, etc., to see if one of them is
causing the problems. Since fluxbox doesn't crash as often you might
work there to clean things up and then come back to KDE to see if it
has helped.

Consider an emerge -C on things you don't absolutely need, like Flash
or whatever you're using, to figure out what's involved. Also, are you
using Firefox 3 or 4? Consider trying the other.

As with other apps, try running Firefox from a terminal and see if it
throws any error messages.

Good luck,
Mark


   



I haven't been ignoring your suggestions but I did try them a bit ago.  
It's in another reply.  Thanks for the suggestions tho.


As for trying to run from a terminal, if I do that, I can't see the 
errors and when the kernel panics, I lose the messages.  Sort of a catch 
22 here.  Would be nice if I could tho.


Thanks.

Its probably just retrying..
adam@sphinx ~ $ cat /proc/sys/net/ipv4/tcp_syn_retries
5

...five times because google's firewall is dropping it (so not
resetting the connection), and IIRC the timeout at each retry
increases (doubles?) so it takes a long time.

Never heard of that file either. Interestingly ping and host dont seem
to read it.
adam@sphinx ~ $ strace ping google.com 2>&1 | grep gai.conf
adam@sphinx ~ $ strace host google.com 2>&1 | grep gai.conf
adam@sphinx ~ $ strace ssh google.com 2>&1 | grep gai.conf
open("/etc/gai.conf", O_RDONLY) = 3
^C

And that's because they're not using getaddrinfo (if grepping strace
output is a valid test)

It makes sense that host wouldn't use it, and it is supposed to just
use DNS not query through the resolution options listed in
nsswtich.conf. I have NFI why ping isnt using it
