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).
Comment 2 darkbasic 2014-09-19 21:42:48 UTC 
'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.

 Seems like, there are many duplicates of bug 75276

I think the framerate drops are due to VRAM thrashing and not directly related to the GPU faults.
