/sys/class/drm/card0/error

and because this bug annoys me, here is another error state, which came up
today.

[25186.039463] [drm] stuck on render ring
[25186.040310] [drm] GPU HANG: ecode 0:0x002883e6, in kwin_x11 [4096], reason:
Ring hung, action: reset
[25186.040312] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[25186.040312] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[25186.040313] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[25186.040313] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[25186.040314] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Could it be, that this is more like a kwin issue?
