Created attachment 68036 [details] screenshot of xorg background corruption, plymouth corruption is similar but moving around When booting linux with 3.2, 3.5.5 or 3.6 and drm-next (other versions untested) the initial framebuffer shows small pieces of horizontal corruption on plymouth and Xorg. This lasts until Xorg completes loading. If you get lucky and the lockup recovery is succesful Xorg works normally afterwards, but the background image is still corrupted until it is changed.

Does it work any better with drm-next? http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next
the dmesg was on drm-next of this morning

I might add that the screen corruption is permanent and doesn't recover at all in my case (Bug 60981). Also, it flickers all over the screen when moving the mouse, playing a video etc. (see the video linked in Bug 60981).
