I have only seen this problem on Linux systems where I suspect that the build
environment didn't match the kernel environment 100% - it seems that libafs is
extremely sensitive to this. 

You may want to try to:
- rm -r /usr/src/linux*;
- untar a kernel source tarball;
- build a new kernel;
- install it, boot it;
- untar an OpenAFS source tarball;
- configure, build AFS ('make dest');
- rm /usr/vice/etc/modload/*;
- copy the newly-built libafs modules (in the dest directory under
  root.client) to /usr/vice/etc/modload.

Now you have 100% guaranteed matching modules, and only by religously
following this routine (or one variation: install the kernel rpm plus the
matching kernel source rpm, using the .config file that's usually installed in
/boot to reconfigure the kernel source tree - 'make oldconfig dep') have I
succeeded in *not* crashing machines with OpenAFS.
