xorg log 

Hi.

I experience quite frequent freezes of the system since I've switched over to
nouveau... :(

This system here runs Debian unstable on AMD64, the GPU is a G86 [GeForce 8400M
G].

Symptom is that X suddenly freezes (although the system seems to keep running
in the back). Mouse continues to work, keyboard doesn't although SysRq is
possible to some extent (well sync/umount/boot).
Going back to console does not work.

I've attached an Xorg.log (although this didn't contain any errors).


Also some kernel log messages, collected from various events:

In this case, it apparently just killed my window manager, falling back to
metacity, and I could somehow cleanly reboot the system

(was just doing some libreoffice stuff,... so there shouldn't have been any 3D
problems included!?)



There usually follows some filesystem corruption from this...
Which makes the whole thing barely usable.


Not sure whether this is related, but I had some severe problems of freezing
nouveau, which seemed to be related with the system going out of main memory.
(Had several VirtualBox VMs started,...) This was quite easily reproduceable.



Any ideas? Or is there at least some way to certainly kill nouveau/X and go
back to a working console?


If you need further data, please tell me which.


Cheers,
Chris.
