/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!

[   20.225866] [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.

Hello James,
Is the bug still present with the last kernel version? If so,could you please attach dmesg with drm.debug=0xe parameter on grub. Thank you.
