Crash dump

GPU keeps freezing and resetting every 10-20 minutes when using an external
display. On older kernel versions it would just freeze with mouse pointer still
moving, on newer ones (>= 4.8) it freezes and resets.

My machine: Dell XPS 13 (9360)

Distribution: Ubuntu 16.04 (preinstalled by Dell)

Kernel version (tried all of the versions mentioned): 4.4 (vanilla), 4.8, 4.9

Currently I have the following setup:
$ uname -mr
4.9.0-040900-generic x86_64

Also, I ran Intel Graphics Update Tool 2.0.3 to update the driver with no
success. 

Also, I've tried switching off the following flags on by one in
/etc/default/grub with no success:  i915.enable_rc6=0 intel_idle.max_cstate=1
i915.semaphores=1 i915.enable_dc=0 i915.enable_fbc=0 i915.enable_psr=0

Kernel log contains the following:

[ 4557.659862] [drm] GPU HANG: ecode 9:0:0x85dffffd, in Xorg [1218], reason:
Hang on render ring, action: reset
[ 4557.659865] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4557.659866] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4557.659868] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4557.659869] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 4557.659870] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 4557.659990] drm/i915: Resetting chip after gpu hang
[ 4557.660068] [drm] RC6 off

Crash dump is in the attachment.

Hope this is enough. Will supply any additional info if required.
