dmesg output

Unigine Valley 1.0 and Heaven 4.0 cause VERDE GPU lockup when
ARB_sample_shading is enabled. With kernel 3.14.19 I got immediate lockup.
3.14.20 allows Valley and Heaven to run for up to 1 min. GPU fails to resume
after lockup, screen becomes corrupted and I need to reboot the system.

If I disable ARB_sample_shading (via env variable
MESA_EXTENSION_OVERRIDE=-GL_ARB_sample_shading) then VERDE GPU do not hang at
all (currently valley is running on my system for more than two hours without
lockups).

I also have BONAIRE GPU and it does not hang.


Software versions:

kernel-3.14.20
mesa-10.3.0
llvm-3.5
