:Just a quick note:  I tested the AHCI driver here and everything works
:flawlessly (until now :)

    What didn't work?  Was there a port multiplier there that it didn't
    recognize?  Or is that Hitachi the only thing connected?

    The failure was in the PM probe code, which is fine if there is no PM
    there (maybe I shouldn't put PM-probe related errors as bootverbose
    only).
