Comment # 25 on bug 98520 from Eugenij Shkrigunov

Sorry for the noise, this information may be helpful.
I have installed mesa-13.0.3, latest Steam beta (with fix libxcb, libX) and
llvm-3.9.1: "Star Conflict" randomly hang whole computer (only SysRq helps).
After downgrade to llvm-3.9.0 "Star Conflict" does not hang computer anymore.
