<pre>I have regular GPU hangs in many applications (like kwin_x11 and chrome) this
is just an example. I seem to be able to mitigate all hangs by disabling screen
energy saving option in powermanagement setup, but then my screens never sleep,
which is a work-around I'm not happy with.

[33805.322716] [drm] stuck on render ring
[33805.323264] [drm] GPU HANG: ecode 7:0:0x85fffffc, in kscreenlocker_g
[14201], reason: Ring hung, action: reset
[33805.323266] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[33805.323267] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[33805.323268] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[33805.323268] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
