dmesg crash log

I get random GPU lockups in Unigine Valley. Sometimes it happens at Test 5 and
sometimes in Test 9. Basically the screen is freezing but music continues
playing. After sometime there is only noise on the screen. The performance went
also down, I saw 57 fps in Test 1 and now only 54 fps.
I also experience something similar during playing Shadow Warrior, in the
Prologue mission, GPU hangs forever.

Bisected this to:
064550238ef0b44e341b2a50c3147f83c2a6d5b0 is the first bad commit

During regression testing I faced

   title="RESOLVED FIXED - Massive graphics corruption with World of Warcraft"
   href="show_bug.cgi?id=101969">https://bugs.freedesktop.org/show_bug.cgi?id=101969</a> where I saw some serious
corruption of the graphics in Valley so I used this patch to overcome
<a href="https://cgit.freedesktop.org/mesa/mesa/commit/?id=b9fc9d3f241758ed8a274be7abf68bf448653508">https://cgit.freedesktop.org/mesa/mesa/commit/?id=b9fc9d3f241758ed8a274be7abf68bf448653508</a>
But its the same issue like in the bug report mentioned above. Seems the patch
hasnt fixed all issues.
