Since people often hit this problem when they first compile a kernel,
the solution ought to go in the FAQ.

/boot/System.map has an incorrect kernel version. :-)
That file is a kind of database that must be kept consistant
with the kernel you are currently running.
This is of course difficult to do when you run multiple versions
of the same kernel. I'd be very happy to spend 80 kB of kernel
memory on a reliable answer, especially when considering just how
big an uncompressed kernel is already. Oh well.

Yep, the System.map file ought to go in /boot with everything else.
It would be even better to move the modules too.

See the ps(1) man page. Your solution works, but only for one kernel
at a time. If you add the version number on the end as instructed,
you are still limited to one kernel of each release. Ugh.

I will guess that this is some sort of Red Hat 6.0 feature.
The normal file would be /boot/System.map-2.2.5 and you could
delete /boot/System.map, but you may prefer to generate a
/boot/System.map symlink at every boot.
