Can you provide a > full dmesg of radeon and/or amdgpu? Sure here from boot with IOMMU/SR-IOV ON/OFF in BIOS : http://ftp.frugalware.org/pub/other/people/crazy/radeon/dmesg-iommu-sr-iov-off.txt http://ftp.frugalware.org/pub/other/people/crazy/radeon/dmesg-iommu-sr-iov-on.txt Also nothing else changed in that setup just testing kernel 4.17. I can force the GPU to use amdgpu if you wish and post dmesg's too.
