[ 66.756009] [drm] stuck on render ring
[ 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 (closed) 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.
