I was investigating this bug https://bugzilla.gnome.org/show_bug.cgi?id=767180
(don't know if there will be any relevance, but thought I would mention it just
in case) and came across the following messages in my syslog:

    Jun 30 22:52:18 <Computer-Name> kernel: [16090.619806] [drm] stuck on
render ring
    Jun 30 22:52:18 <Computer-Name> kernel: [16090.620319] [drm] GPU HANG:
ecode 6:0:0x84fefffc, in gnome-shell [1910], reason: Ring hung, action: reset
    Jun 30 22:52:18 <Computer-Name> kernel: [16090.620321] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
    Jun 30 22:52:18 <Computer-Name> kernel: [16090.620322] [drm] Please file a
_new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
    Jun 30 22:52:18 <Computer-Name> kernel: [16090.620323] [drm] drm/i915
developers can then reassign to the right component if it's not a kernel issue.
    Jun 30 22:52:18 <Computer-Name> kernel: [16090.620324] [drm] The gpu crash
dump is required to analyze gpu hangs, so please always attach it.

So here I am. I am running Ubuntu GNOME 16.04 64-bit with GNOME 3.20 and Linux
kernel version 4.4.0-28-generic. My machine is a Lenovo B590 laptop. I have
attached the crash dump as instructed.
