Lately, sometimes, this is happening in dmesg without doing anything in particular special:

According to Daniel Vetter this should not be kernel related and his first advice is to try out a later mesa state. In my case I will upgrade to mesa-9999 and keep an eye on dmesg.

happened again with:

So either it is kernel 3.5.x related or was introduced at an earlier mesa commit.
Comment 2 Andreas Sturmlechner gentoo-dev 2012-09-09 16:20:40 UTC
I think I've now accumulated enough uptime in 3.4.10 to tell that the error is not present there, so back to vanilla-sources-3.5.3.

Now, I've rebuilt xf86-video-intel with a modified ebuild to exclude UXA (and include _only_ SNA) support and haven't seen the oops for several hours. Previously, unknowingly, UXA was used instead, so that might be related.
Comment 3 Andreas Sturmlechner gentoo-dev 2012-09-16 12:44:13 UTC
After switching to SNA more than a week ago there were no such errors anymore.
Comment 4 Andreas Sturmlechner gentoo-dev 2013-03-03 09:47:58 UTC
Update: Seems the error is here to stay. Still happens after packages were updated to mesa-9.0.3, xf86-video-intel-2.21.x, and through all the kernel versions until 3.8.1 currently.

Please see above URL. Could you try newer versions and report back there to help them test possible fixes to this problem? Good luck and thank you in advance.
