I am uncertain as to if this specific issue has already been asked, and I dunno if this is the right place to ask this so I apologize in advance-
Anyways, I am having this issue where if I power off or restart a VM (assuming it is using the GPU passthrough), the host dmesg logs starts flagging CPU soft lock warnings, and on top of that the entire host becomes so sluggish to the point of being severely unusable (WebUI also becomes unusable). I have tried researching the issue, and people online mention that it might be a GPU vendor-reset issue, however the dmesg logs don't mention anything about failed vendor-resets, in fact it mentions that the vendor-reset executes fine without issues.
My specs are:
CPU: AMD Ryzen 9 7900X
GPU: AMD Radeon RX 7800 XT
RAM: Corsair Vengeance 64 GB DDR5 @ 6000 MT/s
VM Specs:
8 vCPUs
32 GB RAM
100 GB Storage (with other storage drives passed through to the VM)
GPU properly passed through (at least to my knowledge) with the latest AMD Drivers installed in the VM.

That's all of the information I can think of to show. I would really appreciate it if someone could at least point me in the right direction with fixing this issue. I am new to Proxmox, and I love it so far. Thanks in advance though!
