No, I have correct drirc.

Setting this env variable doesn't help.

<span class="quote">> Can you try a newer kernel?</span >
I just tried 3.17.0:
- GPU still hangs if ARB_sample_shading is not disabled.
- It seems lockup detection timeout was increased significantly:
kernel: radeon 0000:01:00.0: ring 0 stalled for more than 91985msec
kernel: radeon 0000:01:00.0: GPU lockup (waiting for 0x000000000000e90a last
fence id 0x000000000000e8fb on ring 0)
- Unrelated to this bug, but.. animation is VERY choppy. I constantly see
several-seconds-long freezes, and sometimes >10 sec long freezes.</pre>
