    As was mentioned in another reply, this message by
    Joerg Friedrich

    gives a possible explanantion of where the time is going.
    I applied the patch to the debian kernel sources for 2.6.18,
    it applied cleanly and fixed the problem.

    I have the upatched kernel in /boot so I can run the tests
