Oops in paging request with 2.2.14

From: Matthew Hanselman (mjhans@quiq.com)

An oops from a 2.2.14 kernel that had an uptime of probably 2 months....

WARNING: This version of ksymoops is obsolete.
WARNING: The current version can be obtained from ftp://ftp.ocs.com.au/pub/ksymoops
Options used: -V (default)
              -o /lib/modules/2.2.14/ (default)
              -k /proc/ksyms (default)
              -l /proc/modules (default)
              -m /usr/src/linux/System.map (default)
              -c 1 (default)

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.

No modules in ksyms, skipping objects
