--- Comment #2 from Paul Menzel <paulepanter at users.sourceforge.net> ---
Today it happened again¹.

1. Some more information about the system:

        $ lspci -s 4:00
        04:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400
GS] (rev a1)

I have another system with an integrated Nvidia device, where I have not been
able to reproduce this.

        $ lspci -s 2:00
02:00.0 VGA compatible controller: NVIDIA Corporation C77 [GeForce 8200] (rev
a2)

2. The same corruptions started some time after startup (no suspend in
between). After some time, I closed Iceweasel/Firefox and the system froze. I
just pressed the reset button and the corruption was right there the next
start. So it might have to do something with the card setup. Then it froze
pretty quickly (after five minutes) without even starting Iceweasel/Firefox and
just awesome WM and uxrvt terminals running. Switching the power supply and
then starting again the corruption was gone and I could not reproduce it again
today.

3. This is a hard freeze, meaning I am not able to ping the machine when it is
frozen.

4. I checked again and the log files do not contain anything before the crash
related to Nouveau or the graphics stack.

5. I am going to try Linux 3.10 from Debian Backports [1], though was not the
Linux Nouveau module rewritten in Linux 3.7 [2], so that this is not going to
point to the problem in Linux 3.2 (with DRM from 3.4.47 [3])?
