Might be this nouveau bug (linux-next at the time was 3.8 now): https://bugs.freedesktop.org/show_bug.cgi?id=58087 I think this was fixed but neither bug report has a cross reference :( The original report is here: https://bugzilla.kernel.org/show_bug.cgi?id=51291 Pekka, Can you please re-assign the bugzilla #51291 above to DRI?
