[   66.757070] [drm] GPU HANG: ecode 8:0:0x85dffffb, in steam [3539], reason:
Ring hung, action: reset
[   66.757072] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   66.757073] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   66.757075] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   66.757076] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

This is a cheap Chinese passiively cooled NUC like computer with an i5-5257U
and Intel Iris Pro 6200.

The OS is Debian jessie with xserver-xorg-video-intel from the backports
(2:2.99.917-2~bpo8+1).
Kernel Linux ishimura 4.2.6 #1 SMP Wed Nov 18 20:21:58 CET 2015 x86_64
GNU/Linux
build from the kernel.org sources.

The Kernel parameter intel_iommu=igfx_off is set but doesn't help. The crashes
are very frequent.
