          Assignee: dri-devel@lists.freedesktop.org
           Summary: Artifacts in kernel 3.16-rc1 and HD 7750
          Severity: major
    Classification: Unclassified
                OS: Linux (All)

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.
