drm error output

On resume from suspend-to-disk, the system will sometimes have a GPU HANG in
dmesg, and a subset of the GUI applications I use will segfault on load until
the system is rebooted.

OS: Archlinux
Kernel: 4.4.5-1-ARCH
Arch: x86_64
Hardware: Lenovo X200
xf86-video-intel-git: 2.99.917+560+gd167280-1

Steps to reproduce:
- Cycle the system to suspend several times.
-- This error usually occurs between three and ten suspends.
-- I have terminator, firefox, and thunar open while doing this.
- Launch Chromium, slic3r.pl, Blender, or openSCAD. The application will
segfault.
