    Hmm... Since there should not be so much I/O on an idle system, I would like to
    ask:
    Did you use
    - iostat
    or
    - iostat 2
    or so?

    If I use "iostat" I just see the average. If I use "iostat 2" I see first the
    average and then the iostat of the last 2 seconds:
    > iostat 2
