So i'm running Unraid as a VM Server with two GPUs installed, a RX550 in slot 4 and a RX6800XT in the first slot.
I want to use the RX550 for the unraid host, so i specified slot 4 as primary GPU in the Motherboard (TRX40 Gigabyte Designare).
It works fine for the Motherboards Bios and grub, but as soon as the unraid-kernel boots it automatically switches to the 6800XT.
The video output of the RX550 gets stuck in the grub menu. So i tried to bind the 6800XT to the vfio-pci drivers at boot via the System Devices tab, with no luck.
Both screens get frozen (RX550 in the grub menu and RX6800XT in the kernel loading screen). Passthrough works fine though.
Are there any workarounds to stop unraid from using the wrong GPU ?
