Error: unknown pci header type ‘127’
This has been occurring to people who updated their BIOS on AMD motherboards. This happened to me across different linux distros (fresh installs) AND motherboards AND GPUs (tested with both 980 ti and rx580). I basically bricked an MSI x470 Gaming Plus trying to force my BIOS to revert to an earlier version to fix the problem, then I was stupid enough to update my BIOS on the brand new Asrock x470 Taichi that I bought to replace it, and the SAME EXACT error occurs on a completely different setup.
This is both a warning and starter thread to see who else is experiencing it and if anyone has any fixes for this, PLEASE share. It looks like the major vendors are locking down their recent BIOS updates for some reason. I was not allowed by the BIOS to revert on both the MSI AND the Asrock motherboard.
