Panic when enabling passthrough QAT on C3xxx under Proxmox

Description
LMK how you want the panic dumps since I'd rather not enshrine them here.

Hello Alex,
Is this an add-in card or a QAT module on-chip with your CPU? Have you verified that it works without passthrough on your hardware via bare metal install?

The hardware in question is an Intel Denverton C3908 box from Qotom. QAT is built-in t that SoC. Yes, I did mess around with it prior to this full passthrough attempt.
