Description:
I experience random crashes with nouveau driver. I have a nvidia Quadro K2000M graphics card. Unfortunately, I have no idea where to start to investigate such bugs, but it seems reporting it should be an ok start.

Additional info:
* package version(s)
xf86-video-nouveau version 1.0.10-2
* config and/or log files etc.
