The DRM driver in the kernel hangs at gnome-shell startup, resets the chip &
then seems to carry on fine after that. 

$ dmesg
...
[   31.021308] [drm] stuck on render ring
[   31.025961] [drm] GPU HANG: ecode 5:0:0xfdffffdd, in gnome-shell [2833],
reason: Ring hung, action: reset
[   31.025965] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   31.025966] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   31.025967] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   31.025968] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I see this bug both with the stock Debian kernel (a patched 3.16) and with
3.19.

$ uname -a
Linux bill 3.19.0-trunk-amd64 #1 SMP Debian 3.19-1~exp1 (2015-02-12) x86_64
GNU/Linux

Upgrading to the latest userspace driver doesn't seem to have helped, although
I haven't tried compiling from git yet:

$ dpkg -s xserver-xorg-video-intel
Version: 2:2.99.917-1~exp1
