xz'ed crash dump

On a Thinkpad W520 using the Intel GPU, playing Zandronum (gzdoom) with the
(graphically intensive) Brutal Doom mod, every 5-15 minutes, a GPU hang occurs.

Usually, the GPU gets reset properly. Sometimes, however, it freezes the entire
system.

Linux Kernel 4.4.0, 64bit, mesa-11.0.6, xorg-server-1.17.4,
xf86-video-intel-2.99.917. No i915 cmdline parameters are in use. TearFree is
used.


The hang was also observed on kernel 4.1.12.


[drm] stuck on render ring
[drm] GPU HANG: ecode 6:0:0x91beffb8, in zandronum [3531], reason: Ring hung,
action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.

I am capable of testing kernel and userspace patches.
