v4.20-rc5+ on x220: Resetting chip for hang on rcs0

[Pavel Machek]

Hi!

Another day, another problem... but this one is different from the
previous hang, as machine survives.

Chromium was running with youtube video playing.

[31850.666274] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[31850.666277] [drm] Please file a _new_ bug report on
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.
[31850.666285] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
