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. |

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).
