Subject2.3.26 oops report
Date
Looks like xntpd and rc5des managed to tickle something after the machine
had been up for about 42 hours. Although it doesn't show up in the
ksymoops output below, there was another disturbing line of syslog output
between the two oopses:

iput: inode 00:00/0 count wrapped

Anyway, here's the ksymoops output...

ksymoops 0.7c on i586 2.3.26. Options used
-v /usr/src/linux/vmlinux (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.26/ (default)
