I don't imagine that it is relevant, but you are getting a couple of MTRR errors. What does /proc/mtrr show?
I've just pushed a patch into drm git which should halt the continuous stream of errors from the GPU, and provide some additional info which may help pinpoint why we get the PGRAPH exception in the first place.
Pierre, do you have problems still? I have a NVS 140M in a laptop and Nouveau is running just fine.
It is working fine these days, so you can close this bug.
Appears fixed, closing. Thanks.
