Subjectdrm/nouveau E[ DRM] fail ttm_validate
Hi,

Right after I upgraded to Ubuntu quantal I started seeing these
messages:
Jan 4 12:18:12 koli kernel: [ 3705.970720] nouveau E[ DRM] fail ttm_validate
Jan 4 12:18:12 koli kernel: [ 3705.970726] nouveau E[ DRM] validate vram_list
Jan 4 12:18:12 koli kernel: [ 3705.970760] nouveau E[ DRM] validate: -12

A few times I had corrupted graphics, and I had to stop X. Restarting didn't
help and I had to reboot.

I'm running my own 3.7.1 kernel, so I also installed the 3.7.0 development kernel
from Ubuntu (3.7.0-7). And that kernel shows these messages too.

With the Ubuntu kernel the graphics corruption is milder. I can continue to work. Sometimes
I get a burst of the messages, but I have no clue how it is triggered.

Now the strange thing is that I was running my 3.7.1 kernel on Ubuntu precise
and I have never seen these messages before. What could be the case is that
xorg is doing something new and that is causing the errors.

xserver-xorg-video-nouveau
precise 1:1.0.2-0ubuntu3
quantal 1:0.0.16+git20111201+b5534a1-1build2
