are broken now in this one.
radeon tells:

Actually Michel came up with a fix for the performance regression which is
now backported to older kernels as well.
So the original issue of this mail thread should be fixed by now.
Sure here from boot with IOMMU/SR-IOV ON/OFF in BIOS :Also I played with BIOS options also which does not fix anything but
changes the error message.
IOMMU && SR-IOV disabled the error changes to this :
[ 7.092044] [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0
test failed (scratch(0x850C)=0xCAFEDEAD)
[ 7.092059] radeon 0000:21:00.0: disabling GPU acceleration
While I could workaround SWIOTLB bugs in 4.15 and 4.16 , 4.17 seems to
kill the GPU with no way
for me to make it work ( at least I could not find any workaround by now )
That actually sounds like something completely different. Can you provide a
full dmesg of radeon and/or amdgpu?

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.
Just let me know
