[1.] Oops: Unable to handle kernel paging request

[2.] Last night I got 31 oops starting at about 6:30am. This is right
when my cron.daily scripts run (which include updatedb and others). This
is an nfs server for my LAN, and I have a worstation that also runs
cron.daily at the same time, and therefore over the nfs volumes (if
this matters). I have not been able to reproduce this at will, though
it has happened several times. The filesystem used for the nfs export
is ext2 (reiserfs and xfs were also used and oops'd too). The kernel
is vanilla 2.4.10-- no patches.

[3.] Keywords: kernel paging

[4.] Linux version 2.4.10-nfs1 (root@hagrid) (gcc version 2.95.4
20010902 (Debian prerelease)) #1 Thu Oct 4 19:35:45 EDT 2001

[5.] This is the first oops message. There are over 1000 lines of the
oops messages that occured. Please let me know if you need more.

ksymoops 2.4.3 on i586 2.4.10-nfs1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.10-nfs1/ (default)
-m /boot/System.map-2.4.10-nfs1 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
