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. -- You are receiving this mail because: You are watching the assignee of the bug.
