I was able to get output by adding this to my kernel parameters: console=ttyS0,115200 earlycon=uart8250,mmio32,0x1c020000 >From there, booting into 4.11, it hung here: [ 4.168868] acpi ACPI0007:07: CPPC data invalid or not present [ 4.175198] GHES: HEST is not enabled!

However, the console is flooded with messages like this: [ 42.982471] pcieport 0002:00:00.0: TLP Header: 60001004 000000ff 00000090 30032000 [ 42.990201] pcieport 0002:00:00.0: AER: Device recovery failed [ 43.156938] pcieport 0002:00:00.0: AER: Multiple Uncorrected (Non-Fatal) error received: id=0000 [ 43.165695] pcieport 0002:00:00.0: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, id=0000(Requester ID) [ 43.177385] pcieport 0002:00:00.0: device [10e8:e004] error status/mask=00100000/00000000 [ 43.185695] pcieport 0002:00:00.0: [20] Unsupported Request (First) I'm happy I can boot now. If I can also stop the errors, that'd be great.
