Just in case..is the NFS mount in a union mount by any chance?
(There is a known bug for NFS readdir under a union mount, because the
 NFS client readdir isn't setting the eofflag. Someone has sent me a patch
 that looks fine, but it hasn't been checked into head yet.)

I'll also grep a head kernel to check to see if anything else (except the
NFS server) uses the eofflag argument to VOP_READDIR().
