    This one is another SMP motherboard.

    I wonder if there are any non-SMP reports at all?

    Mmm.. That one (above) is puzzling. Are you sure?

    WD has a non-announced bug with UDMA support on certain models,
    which I just found out about from reading some "semi-secret"
    material sent to me from a vendor of IDE-interface boards.

    But the drives listed there are the AC35100 and AC36400.
    Or maybe those are the only ones we know about..
    I suppose we'll need to blacklist those models permanently.
