Correction, this GPU hang occurs on 4.12.5, not drm-tip.

Do you have the guc loaded?

Comment 4 doug.bengtson 2017-08-13 16:13:36 UTC 
I've tried both with and without guc i915.enable_guc_loading=1 i915.enable_guc_submission=1 kernel options.  Same result.

The only thing that I have been able to achieve some level of success with is using AccelMethod uxa in xorg config.  That will more often allow OpenGL programs to run with the intel driver without a GPU hang, but it has still occasionally occurred.
