GPU passthrough works but no fan spin, potentially due to missing a couple of PCI devices but I can't find them in QEMU/KVM PCI Host Device

@flyingdoggy Can you confirm the vfio-pci driver is in use for the vega card after boot?

lspci -v -s 0c:00.0 | grep -E '(VGA|driver)'

If you followed the F33 guide see my comment on the initramfs creation.
