I have had GVT-g working before, actually for months on this system. The only thing I think I did is that I updated to kernel 5.14. But even downgrading back down to 5.13 or even 5.12(with b560 patch) did not work. GVT-g keeps on throwing either this error or a bad address error. No matter what the guest is Linux, windows, OVMF, Seabios, Q35, or i440fx all of them do not get past the initial boot screen. NONE make it even close to driver initialization

QEMU Script

!/bin/bash

I tried with a custom compiled kernel and custom compiled QEMU

GVT-g not working, nothing is starting #193
