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.
