Subject[Oops]: Kernel 2.4.17: postfix startup crash, ksymoops output attached

I received the following oops today when postfix (Debian version
0.0.20010502.SNAPSHOT+tls-0.7.2-1) started (well, it tried).

The system is a 700MHz Athlon (not overclocked) using a 10GB IDE hdd
and ext3 jfs. This is my 'workstation' and was under light load only.
Kernel 2.4.17 is built for Athlons.

More details available on request.

Here we go:

[4.] Kernel version (from /proc/version):
