    SubjectAPM and cs4281 sound module

    as I posted here ~2 weeks ago my system locks when going to suspend mode.

    Now I was able to locate the problem in the sound module. (More information
    at EOF)

    When I make a 'rmmod cs4281' suspend and resume works very well.

    System hangs only when suspending with loaded sound module.

    Kernel is 2.4.2-ac20
