GPU crash dump file
Bug description: Having random reboot issues with the system, but usually not accompanied by this GPU hang. Dual displays running @ 4k60. After the random reboots, both displays work during boot but DP1 does not display once X has loaded.
[68833.361334] [drm] GPU HANG: ecode 9:0:0x85dfbcfb, in siemcy , reason: Hang on render ring, action: reset
[68833.361335] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[68833.361335] [drm] Please file a new bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[68833.361335] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[68833.361335] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

email@example.com, there are constant improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa (13) and:
- mark as REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log, & you may also collect and attach logs collected thanks to apitrace: http://apitrace.github.io/)). You may also have a try with i915.enable_rc6=0 in your boot command line parameter.
- otherwise RESOLVED/* if you cannot reproduce (but confirm your final config for traceability)
