GPU crash dump

I have experienced GPU hangs with all kernels after 4.3.

I'm running a MS Surface Pro 4.

Feb 15 17:27:22 hat kernel: [  478.912402] [drm] stuck on render ring
Feb 15 17:27:22 hat kernel: [  478.913345] [drm] GPU HANG: ecode
9:0:0x85df9fff, in gnome-shell [1956], reason: Ring hung, action: reset
Feb 15 17:27:22 hat kernel: [  478.913357] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Feb 15 17:27:22 hat kernel: [  478.913361] [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
Feb 15 17:27:22 hat kernel: [  478.913364] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Feb 15 17:27:22 hat kernel: [  478.913367] [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.
