In some versions of afs, there is/was a piece of code that
*intentionally* got extra refs on the AFS root vnode (e.g. the one
corresponding to /afs). I'm guessing that this code is a (too-) clever
attempt to catch a case where that code was risking an overflow of the
i_count. 

Are you doing something that actually has that many refs on an AFS
vnode? It's possible that you are seeing this bug in action.
