Log dump from /sys/class/drm/card0/error after GPU hang (as printed in dmesg
output).
I see this error intermittently when running the Xilinx Vivado v2016.4 software
on my Ubuntu 16.04 LTS desktop (kernel 4.4.0, Intel core i5-6400 cpu with Intel
skylake-gt2 gpu). Attached the full dump from /sys/class/drm/card0/error as
instructed by dmesg below.
[ 255.622496] [drm] stuck on render ring
[ 255.623115] [drm] GPU HANG: ecode 9:0:0x84dffff8, in Xorg [1006], reason:
Engine(s) hung, action: reset
[ 255.623120] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 255.623122] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 255.623125] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 255.623127] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
