Bug#617907: libgl1-mesa-dri-experimental: random crashes with OpenGL apps

> Or you may want to upgrade to the latest kernel in experimental first.

This was easier, so I tried this. Some "progress": instead of crashing X, it 
now crashes the GPU:

[drm] nouveau 0000:05:00.0: GPU lockup - switching to software fbcon

and makes the machine completely unusable: open ssh connections freeze, new 
sessions cannot be opened (it will connect to the port, but will freeze before 
authentication begins, during host authentication I think), virtual consoles 
cannot be changed etc.

The only things which work are: mpd keeps playing music intermittently (every 
time I press a key, I hear a very short bit of music), tcp connections are 
accepted, ICMP ECHO is replied to and magic SysRq key combinations work (so I 
can sync && umount && reboot).

Note that this is 2.6.38rc7, which was the newest a short while ago. It just 
took me this long to figure out why the machine occassionally freezes. Well, 
it does not really freeze, but you get the point.

I installed 2.6.38-2-amd64 now and will see what happens with it before 
building the experimental libgl1.

I noticed there is a newer X, too: any point in checking if installing that 

Oh, and one more point: this lockup seems to happen much less frequently if I 
do not run opengl apps full-screen but in a window (which might be full-screen 
size, though).
