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.
Comment 1 Vladimir Kazanov 2016-12-16 09:32:17 UTC 
One more thing: it seems that switching to the UXA acceleration method at least postpones the hanging, while slowing things down by quite a bit. I am still testing it, not really sure yet.
Comment 2 Vladimir Kazanov 2017-02-03 08:08:50 UTC 
One more comment: UXA is slow as hell on higher resolutions. But at least it works.

Anybody here..?
Comment 3 Jari Tahvanainen 2017-04-11 08:05:43 UTC 
Sorry Vladimir for neglecting this bug too loooongg. Is the problem still valid with the latest kernel (preferable drm-tip from git://anongit.freedesktop.org/git/drm-tip or 4.10.x from canonical) ?
Yann - please check the crash dump if that tells something about the root cause.
Comment 4 Vladimir Kazanov 2017-04-11 14:53:34 UTC 
Jari,

I've just updated to Ubuntu's 4.10.9 (4.10.9-041009-generic x86_64) kernel and SNA mode did not crash for at least a few hours.

Go figure...
Comment 5 Jari Tahvanainen 2017-05-23 11:21:23 UTC 
Marking this resolved+worksforme based on the previous comment, assuming fixed on 4.10...
