There were a few bugs that could cause this sort of thing to happen. They
have been fixed in -current, but were not in 1.2.1. Unfortunately, the
-current NFS code will not just drop into 1.2.1 and compile, because
of other changes (lookup and mbuf changes for example).

I could mail you some diffs to see if they help.
