If you see a kernel Oops in inode_doinit_with_dentry or a segmentation
fault of afsd, try the following. I'm not so sure whether it's entirely
correct, especially the panic call.

With this patch, I was able to mount /afs und run "ls /afs", but any
access below /afs crashed afsd in function afs_xdr_char. I think I've now
understood why, but have not yet created a proper patch.
