Created attachment 130226 [details] /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!
