    This weird behaviour also can be seen with the BogoMIPS calibration:

    Calibrating delay using timer specific routine.. 6428.32 BogoMIPS
    (lpj=12856647)
    ....
    Initializing CPU#1
    Calibrating delay using timer specific routine.. 103837.25 BogoMIPS
    (lpj=207674508)

    Note, that I never observed that on CPU#0. It always affects CPU#1.
