    Hiding warnings. As Tejun noted in another email, this condition should
    not be happening in the first place.

    If I had to guess, I would say that Arjan's patches assume it is OK to
    treat two ports on a single IDE controller as completely independent,
    when that is not really the reality of the hardware.
