Joing two threads:

This is a good site, i had a butchers through it and came up with this:

"System.map is a file (produced via nm) containing symbol names and
addresses of the linux kernel binary, vmlinux.

Its primary use is in debugging. If a kernel "oops" message appears, the
utility ksymoops can be used to decode the message into something useful for
developers. ksymoops makes use of the System.map to map PC values to symbolic
values.

You may get warnings about your System.map being out of date. This won't
affect normal running (FIXME: does it affect ps l WCHAN ?) but its best to
keep a copy around if there is a kernel bug / hardware failure.

The utilities look in a set of standard places for this file like
/boot/System.map and /usr/src/linux/System.map"

Answering the question on the other thread about what System.map is for.
nice one John.
