relevant part of syslog

Hi, 

X crashes (a few times per day), mostly when switching virtual desktops on NV4B
nouveau. I run debian testing  with nouveau git kernel and git
xf86-video-nouveau from the latest git. Most times the screen freezes and there
is no respondence from mouse-clicks or keyboard, but I can move the mouse.
Sysrq works. Sometimes X just crashes and restarts.

I did not observe this in October, so some early November commits
(unfortunately I did not check which one) must be the responsible.

I attach syslog and Xorg.log, if more is needed or testing required please let
me know. Thanks for your great work, cheers

Andi

It would be helpful if you tried git-bisect to find out which commit broke it
exactly.

Could you attach the full output from dmesg instead of a snippet? (It's fine
if
it doesn't show the crash, just make sure it hasn't wrapped around since
last
boot).

dmesg (no crash so far) 

Hi,

here is dmesg without crash so far. I'll try to bisec git as soon as time
allows (earliest next week...).

Thanks,

Andi

Hi,

I found a bug in my script preparing the kernel package. This bug resulted in
not installing the latest nouveau git kernel. So I ran an older kernel with a
new xf86-video-nouveau git and drm git tree.
After I fixed that, anything seems to work as perfect as before, it never
crashed since three days now. 
So probably this bug can be closed. Sorry for the noise and the false alarm.
Thanks again for your effort. 

Andi
