Comment # 11 on bug 85661 from kdj0c@djinvi.net

I have installed mesa-git, and llvm-svn, and it's working now, no more gpu
lockup.

llvm 3.7svn, Linux 3.19.0-rc7-ge36f014 

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD TAHITI
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.0-devel
(git-0467a52)

I can mark it as resolved.
