--- Comment #4 from Alex Williamson ---
I'm not sure how you're getting to this BUG_ON, but (a) legacy KVM device
assignment is deprecated and (b) the card you've chosen has known reset issues.
You might want to try vfio-pci, which I know can make this card work at least
once per host boot, but you're likely to get a BSOD and IOMMU faults on
subsequent guest [re]boots. The reset problem with this card has been reported
to AMD, but there is no solution at this time.
