04:00.0 VGA compatible controller: NVIDIA Corporation NV44 [GeForce 7100 GS] (rev a1)
The card hung, and then didn't recover properly. Are you able to reproduce this at will? Does it still happen with the latest software (Kernel 3.11, mesa 9.2, xf86-video-nouveau 1.0.9)?
I don't have this card any more. Sorry for the noise.
