[OpenAFS] problem loading linux afs kernel module

[Yang, Haichuan]

I compiled openafs 1.2.9 under linux kernel 2.4.20. libafs-2.4.20.mp.o
was loaded fine on the machine it's compiled on. While trying to install
the client on another machine with kernel 2.4.20, the afs kernel module
failed to load with these messages:

# /etc/init.d/afs start
Failed to load AFS client, not starting AFS services.
# /sbin/insmod libafs-2.4.20.mp.o
libafs-2.4.20.mp.o: unresolved symbol sock_recvmsg_Rsmp_af989c11
libafs-2.4.20.mp.o: unresolved symbol sock_create_Rsmp_c0a425fa

libafs-2.4.20.mp.o: unresolved symbol sock_sendmsg_Rsmp_8fc6af94
libafs-2.4.20.mp.o:
Hint: You are trying to load a module without a GPL compatible license
      and it has unresolved symbols.  Contact the module supplier for
      assistance, only they can help you.

What could be done to resolve these errors?=20

Thanks much.
