I think what happens when you start kvm (or whatever virtual machine
manager you're using) is that the amdgpu driver is unbound and after
Windows shut down the driver is bound again to the hardware.
I guess unbinding fails to release all resources. Can you try without
the virtual windows to just do:
echo 0000:03:00.0 > /sys/bus/pci/drivers/amdgpu/unbind
echo 0000:03:00.0 > /sys/bus/pci/drivers/amdgpu/bind
Does this result in error messages, or a working driver?
Best regards
