Hi

After 4 days of uptime I got the following oops.  Nothing special was happening
at the time.  

Ideas?

Ed Tomlinson <tomlins@cam.org>

ksymoops 2.4.1 on i586 2.4.5-pre1.  Options used
     -V (default)
     -k 20010507195318.ksyms (specified)
     -l 20010507195318.modules (specified)
     -o /lib/modules/2.4.5-pre1/ (default)
     -m /boot/System.map-2.4.5-pre1 (default)
