Looks like I got mine working. Build: Mobo: B450M Mortar Bios: 7B89v1B GPU: RX 460 Was getting the constant header 127 problem and all VMs with the GPU attached even failed to start. Solution: 1. Updated to the latest BIOS 2. Update to custom built kernel (described below ~ its easy just copying a couple files) 3. After that the GPU was able to boot into the VM, but I noticed the screen had graphical tears, and the logs indicated vfio_region_write failed. This was solved by adding a script to ensure unraid didn't try to reserve the only GPU (even though I have the `append vfio-pci.ids`) Following the below guide helped me here (just make a script and run it) After doing the above 3, I finally got it working, and was able to boot back into my Windows 10 Gaming VM. Hope that helps somone, and thanks all!

Can you elaborate on upgrading the kernel as well? What steps or guide did you follow (any help would be appreciated!).
