kernel output

Hi.

I have an issue where Nouveau freezes X.

Sometimes it's then even possible to press the Powerbutton or Ctrl+Alt+F1 and Ctrl-Alt-Ent to get a "clean" halt/reboot.

I'm using Debian sid, which has 3D support now enabled per default.
GPU is:
01:00.0 VGA compatible controller: nVidia Corporation G86 [GeForce 8400M G] (rev a1)

The problem typically (but not only) occurs when the system memory gets low.
Sometimes (but not always) I see flickering before the problem occurs, then typically at some parts where compiz does 3D (e.g. minimising windows, or switching the desktop or so).


I see the kernel output attached in kern.1,... but this differs, with sometimes completely different output.



Sometimes the system does not freeze, but I see the flickering and I just get endless messages like these:
