GPU crash dump saved to /sys/class/drm/card0/error

GPU hangs when using chrome, usually when opening new tab.

Dmesg said:

[ 2056.404562] [drm] stuck on render ring
[ 2056.407972] [drm] GPU HANG: ecode 9:0:0x87cafff2, in chrome [3189], reason:
Ring hung, action: reset
[ 2056.407974] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2056.407976] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2056.407977] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2056.407978] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
