/sys/class/drm/card1/error dump
When trying to boot in Fedora 25 on an z270/i7700k using the iGPU I received
these errors: I do have intel_iommu=on. With IOMMU off I do not recieve the
errors, however I need IOMMU on to be able to pass GPUs to virtual machines for
workloads. Please let me know if there is any other information I need to
provide. Thanks!

[ 20.225865] [drm] GPU HANG: ecode 9:0:0xe6ccd35a, reason: Hang on render
ring, action: reset
[ 20.225866] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 20.225867] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 20.225868] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 20.225869] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
