gpu crash log
I had GPU hang and restart with the following text in the journal.
[drm] GPU HANG: ecode 9:0:0x84dffff8, in Xorg , reason: Hang on render ring, action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[drm] GPU crash dump saved to /sys/class/drm/card0/error
drm/i915: Resetting chip after gpu hang
[drm] GuC firmware load skipped
The CPU is an Intel Core m7-6Y75 with HD Graphics 515
Running Linux kernel 4.8.7
There are constant improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa (12 or 13) to see if this issue is still occurring. mark as REOPENED if you can reproduce and RESOLVED/* if you cannot reproduce.
In parallel, assigning to Mesa product.
Platform: SKL (pci id: 0x191e, pci revision: 0x07, pci subsystem: 1043:1cfd)
Mesa: [Please confirm your mesa version]
