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
     -V (default)
