dmesg output after crash
The system randomly freezes. I can still move the mouse but can't do anything
else. I cannot switch VT, the three-finger salute does not work and system shut
down via ACPI does not work either. The only way of recovery is a hard switch
off.
The crash seems to occur more frequently, if I play videos (mplayer or Flash),
but this is not a requirement.
The crash does not occur, if I use the blob firmware
(nouveau.config="NvGrUseFw=1").
