This one, at least, makes a difference.
I now see
[ 2.420000] pci 0000:01:00.0: BAR 5: assigned [mem 0x60000000-0x600001ff]
which is promising.
However it gets to:
[ 8.620000] pci 0000:00:00.0: enabling device (0004 -> 0006)
[ 8.640000] ahci 0000:01:00.0: enabling device (0000 -> 0002)
and hangs.
Full dmesg pasted below.
Thanks,
