For some time, I'm seeing a tiled output like: http://www.fi.muni.cz/~xslaby/sklad/panics/bad_tile.png
This happens sometimes when I open selected pages in firefox. Like maps above.
Currently I'm running 3.2.0-rc3-next-20111130. This started appearing after I switched to desktop fx. Will anything from the debugfs help to track this down? Or better to report this to freedesktop.org?
Please test the patch Chris already replied with to your first mail. It might fix your issue here (if it's just a fence being stolen a bit too early). If that does not help, I'll have to stare at the picture some more to decode the type of tiling/swizzling going on. Maybe different pictures of corruptions might help for that.

Something is pretty decently broken here. Can you please file a bug at freedesktop.org against the i915 drm? A few other things - Can you check whether upgrading the ddx to 2.17 fixes this? Also please attach your Xorg.log and full dmesg. - Please grab intel-gpu-tools.git from
http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/
and attach the output of tools/intel_reg_dumper to the bug report. - If you're using swap, can you check whether disabling it works around the issue?
And please put me as the assignee of the bug.
Thanks, Daniel
