[ 66.622400] [drm] GPU HANG: ecode 9:0:0x85dffffb, in X , reason: Hang on render ring, action: reset
[ 66.622402] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 66.622403] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 66.622404] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 66.622405] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[ 66.622406] [drm] GPU crash dump saved to /sys/class/drm/card0/error
Happens all the time after starting X (after a minute or so). Virtualbox is installed so that taints the kernel I guess, but I post the /sys/class/drm/card0/error anyway.
This is on a Dell XPS 9550.

Can you please try with intel_iommu=igfx_off
Mads, please retry as Chris is advising: with intel_iommu=igfx_off on your boot command line.
There were also improvements pushed in Mesa that will benefit to your system, so please re-test with latest Mesa to see if this issue is still occurring.
In parallel, assigning to Mesa product (please let me know if I am mistaken with this GPU Hang).
Platform: Skylake (pci id: 0x191b; PCI Revision: 0x06; PCI Subsystem: 1028:06e4)

It hasn't crashed yet when I booted with intel_iommu=igfx_off.

Crash when using chromium, this time without any connected monitors/docking stations.
This is _not_ with intel_iommu=igfx_off, I thought I should upload one more crash with less hw connected.

By the way, is this a fix or workaround? :) Does this have any caveats other than not being able to use the graphics controller inside of a VM?
I guess I also must mention that your tip with intel_iommu=igfx_off also solved another bug I reported: https://bugs.freedesktop.org/show_bug.cgi?id=97211
Now the only issue I have left with my XPS 15 is https://bugs.freedesktop.org/show_bug.cgi?id=93578
intel_iommu=igfx_off is not fix of this defect, it is just avoiding it
btw dup of bug 89360?
I saw the same kind of messages in dmesg, so I would guess this is a duplicate of bug 89360 yes...
