Created attachment 101360 [details] Image showing the artifact I have updated the kernel to 3.16-rc1 and got some screen artifacts. I have bisected the problem and found that the commit 1aab5514ca9604e0263f658a067da0189c86a35b (drm/radeon: rework page flip handling v3) is causing these artifacts. I am attaching some images to show these artifacts. There is also a artifact in steam logo inside Portal 2 (the background texture seems to disapear) that does not happen in commit just before (1a0e79184132c5dc0e03a4047eacecc52c24deae). I got 2 freezes too. The computer does not respond anymore, I can't switch to console and after some seconds the computer reboots. But I not sure if this problem is in this commit (1aab5514ca9604e0263f658a067da0189c86a35b).

Please attach the Xorg.0.log file and the output of dmesg, preferably captured after the problem occurred.
Can you try if it still happens with Alex's drm-fixes-3.16 tree?
Yes, it fixes the artifacts with drm-fixes-3.16, but the reboots are still there. I will see if Xorg.0.log or dmesg show any error. I will have to use another computer to do it.
I will open another bug to cover the crash when I have more info about that. For now, the artifacts are fixed.
