    I got the following oops, i can reproduce it:

    my network:

    laptop+modem ----- mybox

    I switch on internet connection, surf a little(network traffic),

    then i shut down the modem, and one minute later when a swap request

    should be done, the oops occurs. My box is not heavily memory stressed

    when the oops occurs. I can also reproduce it by leaving the X screensaver

    running after 1 minute of inactivity.

    the oops:

    ksymoops 2.3.4 on i686 2.4.0-test9. Options used
