Strange messages

[dan Murphy]

Hello.
   I have a question about certain messages I receive from time to 
time.  Now and then, on any given console I will get a message saying "can 
not handle kernel paging request."  then that dconsole is frozen untill I 
reboot.  If I go to another console and log in as super user to try and 
kill the process, that 
console also freezes.  It's not something that I can reproduce regularly. 
I am running Slackware 10.2 kernel 2.4.31.  It is one of the kernels from 
the installation CD.
Any thoughts?
Thanks.
