Public bug reported:
Lucid worked fine on this system, however since wiping over it with a
vanilla install of Kubuntu Maverick 32 bit, every 5-20 minutes the
kernel just hangs. I say it's the kernel as even Alt+Sysrq+RSEINUB does
nothing. Anything animating on screen freezes and any audio playing
stops, ruling out it being something like just being the mouse and
keyboard.
If you look at the kern.log, the last hang happened at 8:45 on Nov 8
(today) and there seems to be a number of stack traces and similar in
there, however I lack any skill to read them. The system was only just
installed, and so is very close to vanilla. The only real changes have
been updating all packages in the standard repo's and using nomodeset
and radeon.modeset=0 as KMS seemed to make things run very sluggish.
Xorg also restarts frequently (whenever I type a URL in rekonq, or come
out of full screen video playback), although I think this is a separate
problem as the kernel doesn't lock up in that case.
Touch also doesn't work, however I read that this is a known problem
from part of the driver being accidentally left out at the last minute
by Ayuthia, and I haven't bothered to run his fix yet. Just mentioning
in case it's related.
I'll try the upstream kernel and see how that goes. Any other questions
/ suggestions welcome.
