Created attachment 106566 [details] dmesg I have an HD 7950 with latest graphic stack from git, including LLVM 3.6 git from today. kernel is drm-next-3.18-wip from today (3.17.0-rc5-drm-next-3.18-wip). I was running some benchmarks (http://openbenchmarking.org/result/1409197-SO-1407298SO78) while I noticed sometimes the picture froze and then after a second or two it kept running the benchmark ultra fast. when the benchmark finished I noticed lots of GPU faults in dmesg: https://paste.lugons.org/show/5981/
I forgot to say you have to run Xonotic with the Phoronix Test Suite "Ultimate" settings (which should be everything maxed out).
'relief mapping' causes the GPU faults, anyway even without this setting the framerate still drops to 0 in some points of the benchmark
Reproducible on Kabini, does not happen with llvm 3.5 so it is probably current llvm regression.
Isn't it a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=84089 ?
