I think you forgot to install drirc from Mesa. What happens if you set this env var?
No, I have correct drirc.
allow_glsl_extension_directive_midshader=true
Setting this env variable doesn't help.

Can you try a newer kernel?
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.
