Need helps with Windows 11 VM and AMD RX560 GPU Passthru!

[caynam]

I created a Windows 11 VM, using 4 cores 8 threads and 16GB of RAM.

Inittially, I used Vitual Graphic Card and everything work fine, no problems whatsoever. 

However, when I passthru my AMD RX560 GPU to the VM, I have problems. I can boot up to Windows, install graphic driver for the GPU and even play some games using Parsec / Windows remote desktop. Problem is, I can not shut down the VM properly. When I shut down the VM, it just freeze and I can no longer access to the VM tab anymore. When I tried to Force Stop the VM, the Unraid Server get frozen too and I have to unplug the server and restart it manually. 

I guess the AMD GPU has some conflics with other components of the server, but I'm not sure which.

I tried different configs with the VM, but no avails.

Here's the system log file for your reference.

 

Please help! Thanks
