--- Comment #3 from Arek Ruśniak arek.rusi@gmail.com --- This is very strange things Tom. This morning i tried mesa-git 2397a72 & llvm-svn r227384 without success. Now i've tried mesa-git 765cfe9 & llvm-svn r227463 and there is no gpu faults anymore.
I'll tried latest llvm-svn ASAP. If you need dumps still i'll do it. But problems are gone for now.
