When using KiCad's Pcbnew program, after a while the screen freezes for a few
seconds, then the window manager restarts. The output of dmesg instructs to
file a new bug, so here it is.

The output of dmesg shows the following:

[ 2359.835457] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [1085], reason:
Hang on render ring, action: reset
[ 2359.835461] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2359.835463] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2359.835465] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2359.835467] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I am using Ubuntu 16.10 with kernel 4.9. This is the output of "uname -a":

Linux spectre 4.9.0-040900-generic #201612111631 SMP Sun Dec 11 21:33:00 UTC

I have attached the GPU crash dump from /sys/class/drm/card0/error, and here is
the output of lspci:
