    This is 100% reproducible on my box so I'll try to figure out what's up tomorrow
    (unless someone else does it earlier ;-)). Now I can only say it did not happen
    with 2.6.14-rc5-mm1.

    Once the box has not suspended due to a process refusing to freeze, but I was
    unable to trace the problem at that time. This does not seem to be readily
    reproducible, however.

    Greetings,
    Rafael
