I haven't seen any bad effects from this, but dmesg says my GPU froze and was reset.

[Mon Jun 24 02:01:15 2019] i915 0000:00:02.0: GPU HANG: ecode 7:1:0xfffffffe, in Chrome_InProcGp [2585], hang on rcs0
[Mon Jun 24 02:01:15 2019] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[Mon Jun 24 02:01:15 2019] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[Mon Jun 24 02:01:15 2019] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[Mon Jun 24 02:01:15 2019] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[Mon Jun 24 02:01:15 2019] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Comment 1 Chris Wilson 2019-06-25 15:48:04 UTC

  IPEHR: 0x0c000000 => fault on context load. 

Could be a bad context image, or more likely we've angered the GPU.
