Thanks for the hint Michel.

But, ughhh...
...in the minute it WORKS without a hitch!

I'm running a new LLVM compilation with 4 cores and thought try it.

System spec:
Mesa 10.6.0-devel (git-cb25087)
libdrm-2.4.59 (minor distro update on 24th)
Linux 4.0.0-rc1-2.g1133f88-desktop+ (drm-next-4.1, 50c7535, 23 hours 
ago)

I'll freeze LLVM (do not install latest compile) and try to bisect Mesa 
(?) 'cause kernel and libdrm did NOT changed compared to tests last 
night.
