Hi!

If I pass through either 3060 the vm works fine,
I can pass through both and the vm is fine, as long as I've installed a third graphics card (amd old card) and set that in the computer bios as the primary card.

2 cards in teh system both passed through results it it not even getting as far as the proxmox uefi splash before hard locking up...

I've spent an evening googling and putting various things in various files (grub, blacklisting, all sorts!) but nothing helped.

Is there a definitive answer as I'd like to remove the amd card and free up a pcie slot you see :)

Thanks!
