[OpenAFS] afsd, openafs 1.1.1, linux kernel 2.4.9, Pentium problem

[Dr A V Le Blanc]

I have been moving my (Debian potato) machines to kernel 2.4.9,
and I have openafs modules which have up to now worked well on
other machines.  On one machine, however, I have a problem.
(Linux avl1 2.2.19 #1 Fri Apr 20 13:44:29 BST 2001 i586 unknown
 /lib/libc-2.1.3.so, vanilla kernel)  The afsd is from the
standard .deb version 1.1.1-0.potato1.  Starting /etc/init.d/openafs
runs fine until

     start-stop-daemon --start --quiet --exec /usr/sbin/afsd -- -stat 2000 \
        -dcache 800 -daemons 3 -volumes 70

at which point I get this:

Unable to handle kernel paging request at virtual address c293a000

Can anyone explain this?  The same afsd works on other machines with
the same kernel and modules, and works on this machine with kernel
2.2.19 with appropriate modules.
