Is there any way ye
When I use a 2.6.12.2-bb4-skas0 uml on an unpatched smp 2.4.31 host, I
have to use "mode=tt". If I let it use skas0, it crashes with:
VFS: Mounted root (ext2 filesystem) readonly.
Kernel panic - not syncing: get_skas_faultinfo : failed to wait for
SIGUSR1/SIGTRAP, pid = 27275, n = 27275, errno = 0
I applied the -bb8-skas0 patches to 2.6.12.3 (omitting
uml-revert-fork-instead-of-clone.patch because it's already in
2.6.12.3). It's been running well, but I just got this crash while the
guest was running "tar c":

Has any thought been given to just choosing a random mac? I haven't
looked closely, but it seems

...or not. It doesn't let the guest transmit, does it? I've never tried
it.
It would be cool if a uml pcap interface could be attached directly to a
saved 'tcpdump -w' packet dump

In 2.6.16, the kernel allows user-selectable address space splits. I
have 1.5G of memory, so choosing 2G/2G lets me turn off highmem. I also
have the new 2.6.16 skas3 v8.2 patch applied.
With this configuration, all umls die immediately, whether I try skas0,
skas3 or TT.
Is this something uml ca

I see. Do you know whether a single uml binary can support arbitrary

With a nonstandard memory split? Jeff said skas3 + no-TT + non-1/3 splet
should work, but I haven't tried it yet.

Are there remaining problems with running a skas3-patched amd64 kernels?
I'm considering doing that, and I know there were problems with it in
the past but I don't know whether they're still around.

...you knew this question was coming. :)
The current 2.6.16 patch has a reject in arch/i386/kernel/sys_i386.c
when applied to 2.6.17-rc5, and that's a file I don't mess around in.
(i'm looking at
http://www.user-mode-linux.org/~blaisorblade/patches/skas3-2.6/).

maybe it's time to finally call it 2.6.17-skas3-v9? and dispense with
the -pre stuff?

Does it work if you do this:

Is anyone still using skas3 on modern kernels? I've been booting on
2.6.23 with noprocmm to avoid crashing with "Kernel panic - not syncing:
switch_mm_skas - PTRACE_SWITCH_MM failed, errno = 22".
