   Hi When I try to take Gpu passthrough with a gtx 1070ti on an Asrock rack B650D4U3-2L2Q motherboard and amd ryzen 9 9950x Cpu with windows 10 VM hypervisor os is Xcp-ng 8.3

I get the drivers installed fine without errors but after reboot I get an error triangle in the windows device manager-. error43 and no image on the screen

have Iommu and svm enabled in the bios

Wasn?�t Xcp-ng 8.3 related or windows drivers I think.

Tested with another PC with Xcp-ng 8.3 and everything worked immediately. So think it must be Asrock rack B650D4U3-2L2Q bios related or ipmi trying to use the same gpu.

Have even copied working win vm from the other pc that this worked on. to the PC with the asrock motherboard and started the vm same error.

Also tried an old Radeon HD 5450 with which everything worked as it should and got a picture on the screen

	Windows vm often freezes and hangs also because of the video driver. Also tried Gpu passthrough with built-in Amd gpu in the cpu as windows freezes and hangs after only a few seconds after logging in
