    That _should_ have been fixed in the last update to ata_piix. If you
    could get Stuart to re-test and re-submit that patch if necessary, that
    would be useful.

    Geert, two things to try:
    1) Try the latest kernel
    2) Fiddle with BIOS settings until your PATA and SATA devices appear as
    _separate_ devices on the PCI bus.
