hi,

i think an alternative to ntpdate:

date -s "`rsh $buildhost date`"

where buildhost is your nfs/ distcc server, or whatever. then
you can sync clocks on your local net, at least.

___

also, i looked at those status pages. one note: i have experience
the machine will not shutdown or halt, but hangs. this is more
annoying on the quadra630 which has no off switch, the only
way to stop it is to reboot into macos. but my performa475/quadra605
can be switch off (i have not tested etch there yet).

i do not experience the clock problem forcing fsck. this only happen
if people have ext3 on their root partition ? anyway i have a single
debian partition of ext2 and i don't get fsck every time. i only
use ext3 when i have a separate partion for more room such as
home or source. the story on ppc list was debian reccomends against
ext3 root (or anything other than ext2).



one question:

so if sonic driver is ok now, would that be a better / faster one
than the Asante or Farollon chips. have one asante card now,
between two machines. could buy a sonic. costs a little bit more.

_

one more comment on RAM

i think 32MB is that OK ? i found that sarge could boot with
20 but it was not happy. to run emacs (xemacs = better) say.

i think i need at least 64 for etch, bare minimum.

If ntpd can't keep sync (?) I guess you'd have to. I'd be a bit worried
about back-stepping the clock during make, though.

Indeed. I guess it is the most important bug to fix of all the outstanding
bugs.

I've finally put up the mac status info that I have collected.

   http://www.mac.linux-m68k.org/status/

...there's more on the Q950 issues there.

If you have ntpd running on $buildhost, you could also do
ntpdate -b $buildhost

There was an old version of one of my IRQ patches that would hang the 
NuBus when a slot driver (e.g. SONIC) was closed. Since the IDE interrupt 
is also on a NuBus slot, this would lock up the shutdown process. It won't 
affect SCSI machines in the same way.

My 630 had the problem too. I fixed the problem, but I don't know which 
patches are in the debian kernel. You could try this 2.6.20 kernel 
instead,

Either one should work fine, but I would expect the SONIC driver to be 
marginally faster since it uses a zero-copy algorithm.

Did you try it with 32 MB? I haven't installed etch yet...
