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 [3440], 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.
