[Bug 64201] OpenCL usage result segmentation fault on r600g with HD6850.

--- Comment #22 from Aaron Watry awatry@gmail.com --- I've gone back to kernel 3.6.11 and still get GPU locks when running this program (and the min() CL builtin in piglit).

I'm leaning towards the issue being in mesa, which I'll have a much easier time bisecting than kernel changes.

Tom, I've also verified that the LLVM .so version is correct (after deleting the old one and rebuilding mesa).

I've tried Alex's patch as is, and also when swapping in the commented line in evergreen_compute.c... It still locks, but we'll see if I can bisect to find a culprit.
