Issues passing RX 560 GPU to a Linux VM

  Linux kernel vendor specific hardware reset module for sequences that are too complex/complicated to land in pci_quirks.c

First thing I tried was the vendor-reset kernel module on the proxmox host. This particular video card (among many of its relatives) has a bug where the card doesn't get properly reset when "stealing" it from the host system to pass to a VM. This kernel module will do that every time a VM using an amdgpu card is started.

So at this point, I think the issue is a bug in the amdgpu Linux driver that only appears when you're running it within a proxmox VM (possibly with literally this specific card model; someone here had nearly the same issue with the same card) and not using it as the primary display. I'll try submitting a bugzilla ticket and update this post with a link, but I have a feeling that due to how specific this bug is, fixing it probably won't be a high priority :(
