The problem doesn’t exist on IVB,BYT and HSW-D. Please see xorg.0.log, dmesg.log and i915_error_state.log. It’s Mesa regression, but it can’t be fixed by installing Mesa (good commit). Only in place of i965_dri.so, it can be fixed. So I can’t bisect. The Mesa good commit is git- 73c78c5, the bad commit is git-7c3138a. Reproduce steps: --------------------------------------------- 1.xinit& 2.export LD_LIBRARY_PATH=bin/:$LD_LIBRARY_PATH export force_glsl_extensions_warn=true 3.vblank_mode=0 ./bin/Sanctuary -video_app opengl -data_path ../ -sound_app null -system_script sanctuary/unigine.cpp -engine_config ../data/unigine.cfg -video_mode -1 -video_fullscreen 1 -extern_define PHORONIX -video_width 1920 -video_height 1080

Just in case hangs are so random that 73c78c5 actually isn't good commit, could you try reverting commit listed in bug 75207, and see if that helps?
The problem also exist on HSW Desktop.

If reverting that fixes the issue, I would assume this to be same (duplicate) bug?

Fix to bug 75207 was commited already to Mesa, can you still reproduce this issue? (if not, please mark this as dup of bug 75207)
Bug 75207 > happened on HSW GT3e for me. I think Tapani had it on GT3e too. With the patch(git-171ec95) that the problem can works well.
