 Looks reasonable, I suppose =E2=80=9Cnfs_lookup+0x6ae=E2=80=9D is in =
 nfs_lookup:
 
         if (cnp->cn_nameiop !=3D DELETE || !(flags & ISLASTCN)) {
                 nfs_cache_enter(dvp, newvp, cnp);
         }
 
 On the NFS server, what do you get from these commands on the exported =
 directory:
 
 ls -ldi /xxxx/.
 ls -ldi /xxxx/.zfs/.
 ls -ldi /xxxx/.zfs/..
 ls -ldi /xxxx/.zfs/shares/.
 ls -ldi /xxxx/.zfs/shares/..
