[OpenAFS] AFS Client Segmentation Fault

Greetings,

I tried to setup an AFS server via the website instructions, but I have
run into some problems.  The server looks to be working fine, but if I
try to setup the same system to be a client to the Cell, it seg faults
every time I try to start it.  The system I am running on is Red Hat 8
with a custom 2.4.18 kernel if that helps.

When I try to run the program, this is the error I get:

afsd: Cannot find "unregister_filesystem" in file /proc/ksyms

I checked in the /var/log/message file and the following error is shown:

Any thoughts?  I will gladly supply any information needed to assist.

Thanks in advance,

Cheers,
