Comment (by mmlr):
OK that clears up that anyway: There's a PCI Express node below the south
bridge that holds a routing table and the HDA Controller. This one is
completely ignored right now. This is because usually these aren't
separate but part of the overall PCI bus, as that's where they are
attached and enumerated. Adding support for that may fix this, but the
issue of the wrong bus number remains curious.
That you have to boot with noacpi and noapic in Linux does not make me
very hopeful though as that usually indicates something's broken with the
ACPI tables. We might just get by, as we rely on ACPI less currently, but
eventually this sounds problematic. With those two disabled the output of
dmesg would be uninteresting indeed.
Have you checked if there's a firmware update available? Sometimes they
fix up the ACPI tables afterwards.
