relevant dmesg part:

[174848.021627] [drm] GPU HANG: ecode 7:0:0x19f669dc, in chrome [7021], reason:
Ring hung, action: reset
[174848.021629] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[174848.021629] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[174848.021630] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[174848.021631] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
