UM 790 pro: Need to reaboot each time to have it working

[odror]

I have the same Setup on ubuntu 24.04
The only CPU configuration that worked for me is hypervisor default, which is qemu64

I can get the VM to use amd gpu after boot.. If I restart the VM, it will stop using the amd gpu and I have error 43
Basically I need to restart the computer each time that I need the passthrough to the amd gpu.

Has anyone find a solution for this "error 43" problem.

Hey yes that is a known issue, it’s the AMD reset bug and there is little you can do about it

Did anyone try to reset the card by redoing all the reboot operations for the gpu without rebooting.
As it is now I may as well dual boot with windows.

I have also tried using virsh nodedev-detach attach to restore the gpu back to the OS, but was unsuccessful. Any tricks with that or workaround will be appreciated.
