Comment # 8 on bug 90378 from Daniel Scharrer

I have confirmed that the issues is still the same with Mesa git-ff0a41b + LLVM
r241381: L4D2 has glitches and lockups with unpatched LLVM and no glitches or
lockups with unpatched LLVM and R600_DEBUG=switch_on_eop.

However other source engine games (Counter-Strike: Global Offensive and Team
Fortress 2) still have similar-looking glitches even with patched LLVM *and*
R600_DEBUG=switch_on_eop. No idea if those are related though.
