--- Comment #4 from Alex Deucher agd5f@yahoo.com --- Are you sure it's the 2D tiling commit? Does just reverting that commit fix the issue? I think it's probably another commit. Does your tree have: http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=39eac3104c... Can you try again with git master?
