[Bug 88301] Dota causes GPU fault and kernel hang

https://bugs.freedesktop.org/show_bug.cgi?id=88301

--- Comment #4 from Tilman Sauerbeck tilman@code-monkey.de --- (In reply to smoki from comment #3)

I can reproduce this on Kabini with current proper mesa and llvm, but not with Tom's perf-Jan-08-2015 llvm + vgpr-spilling-Jan07-2014 mesa branches it works fine there.

Indeed, switching llvm to perf-Jan-08-2015 fixes the GPU faults.

For the record, with my Mesa installation from git master I do get

Warning: Compiler emitted unknown config register: 0x286e8

in glretrace, but that doesn't seem to cause any visible breakage.

Should I leave the bug open until the fix hits LLVM trunk?
