Hi,
Right after I upgraded to Ubuntu quantal I started seeing these
messages:

Jan 4 12:18:12 koli kernel: [ 3705.970726] nouveau E[ DRM] validate

This is userspace bug. See below.
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
(Please do not use distro codenames when reporting bugs upstream)
Quantal, being newer release than Precise, ships much older Nouveau DDX, WTF?
You used some PPA with Precise?
Sorry about that. That was a typo. I meant to say:
quantal 1:1.0.2-0ubuntu3
precise 1:0.0.16+git20111201+b5534a1-1build2
0.0.16 is known to behave like that - you need to upgrade to >= 1.0.
In other words, I have >= 1.0. But you suggest that it shouldn't
happen with >= 1.0
Should I report it on the nouveau list at freedesktop.org ?
