    That looks like junk from somewhere.

    So we were issuing a command, we called the oldpiix code, it decided that
    the timings were not loaded for this drive (ie it was those loaded for
    the other device on the bus)

    It will then have gone into oldpiix_set_piomode which ran succesfully
    implying that ap and adev were valid at that point but seem to have
    mysteriously gone invalid later.

    No idea, and the fact that changing things like the pre-empt behaviour or
    build options makes me wonder if it was scribbled on from elsewhere.
