Another problem on X220.

Chromium was running with youtube video playing.

entire gfx stack, including userspace.

bugs.freedesktop.org against DRI -> DRM/Intel
[31850.666279] [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
[31850.666282] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.

Comment 2 Chris Wilson 2018-12-29 20:47:48 UTC
blt commands on the rcs; more than likely a secondary effect of the list bogons.
Comment 3 Lakshmi 2019-02-13 11:45:40 UTC
Reporter, how often you see GPU hang if not random? Are there any specific steps to reproduce this issue?
Comment 4 Lakshmi 2019-03-07 12:54:11 UTC
Reporter, can you answer to Comment 3?
Comment 5 Lakshmi 2019-04-12 08:47:17 UTC
No feedback from more than 2 months. Closing this bug as WORKSFORME.
If this issue happens with latest drmtip, please attach dmesg from boot and error file. ALso, following information would be useful:
How often it occurs the hang?
Any particular way to reproduce this issue?
What is the impact of this bug? Needs a force reboot after hang or system recovers after hang?
