Ok, I'll mark this as resolved then :)

Thank you, a full dmesg log would be very useful.  It'd be even more useful if you were able to load the drm module with debug=1 :)  When you do so can you please file a new bug, as the original issue mentioned here is fixed.

--------------------------------------------------------------------

Xorg.0.log says:

Fatal server error:
Detected GPU lockup

While dmesg says:

[drm] Allocating FIFO number 0
[drm] nouveau_fifo_alloc: initialised FIFO 0
[drm] PFIFO_DMA_PUSHER - Ch 0
[drm] Allocating FIFO number 1
[drm] nouveau_fifo_alloc: initialised FIFO 1
[drm] PFIFO_DMA_PUSHER - Ch 0

Full dmesg w/debug=1 for the drm module coming shortly...
