Thank you fullzero for your awesome work.
Having configured the BIOS according to the guide and added "pci=noaer" as well as "pcie_aspm=off" to the grub boot parameter, I can successfully boot the machine. Currently I face a few problem with my 12 R9 390X rig. First, it boots into low graphics mode, which isn't too bad as there is still a terminal for me to run oneBash. However oneBash always hangs here.

Any hint on how to solve these problems?
