    Olaf will tell us (I don't have the hardware) but it's indeed a typical
    thing .... From my experience, Adaptec tend to very easily throw PCI
    aborts at you if it doesn't like something in a register access (which
    isn't necessarily a bad thing btw, other vendors are more lenient tho),
    and Macs are well known to Machine Check the box when getting a PCI
    error while most x86 boxes silently ignore them...
