[OpenAFS] kernel Oops - easy to reproduce

[Marc Schmitt]

Hi all,

Maybe this has been reported yet:

I`m using RedHat 7.1 with OpenAFS 1.2.2-rh7.1.1, tried with several 
kernels (2.4.9-6, 2.4.9-12, 2.4.9-21, 2.4.17). NIC is an eepro100.

To create a kernel Oops, simply do the following:
- /etc/rc.d/init.d/afs stop (AFS shuts down properly)
- rmdir /afs
- /etc/rc.d/init.d/afs start
(Found libafs-2.4.9-21.o from SymTable... Loading...
Starting AFS services.....
afsd: All AFS daemons started.
afsd: Can't mount AFS on /afs(2))
- lsmod shows libafs-2.4.9-21       396768   0  (unused)
- rmmod libafs-2.4.9-21 (Oops)

The machine won`t recover properly, trying to start AFS in this state 
gives on my machine the following:
