FYI, the bug is not resolved in the latest kernel package (update 12/23/2017):

> $ uname -a
> Linux N360-11 4.9.0-4-amd64 #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23) x86_64 GNU/Linux

After hibernate/resume:
> $ dmesg | tail -n 9
> [ 1686.964009] IPv6: ADDRCONF(NETDEV_CHANGE): wlp2s0: link becomes ready
> [ 1687.868696] [drm] GPU HANG: ecode 8:0:0x5fa3bf07, in Xorg [650], reason: Hang on render ring, action: reset
> [ 1687.868704] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
> [ 1687.868708] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
> [ 1687.868712] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
> [ 1687.868716] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
> [ 1687.868720] [drm] GPU crash dump saved to /sys/class/drm/card0/error
