Hmm. I doubt that as I can reproduce the same problem (at least the mount 
hanging, not necessarily the errors) with .30, which I presume is before 
the merge.

I have seen the errors too, but that may have been with 2.6.31 (though 
definitely without NFS_V4_1). I seem unable to reproduce those with .30.

On the server (.30) in /etc/exportfs:
/srv/exports         10.19.66.0/24(rw,subtree_check,sync,mp,nohide)
/srv/exports/data    10.19.66.0/24(rw,subtree_check,sync,mp,nohide)

# exportfs
/srv/exports         10.19.66.0/24
/srv/exports/data    10.19.66.0/24

On the client (.30.2):
# mount thorin:/data /mnt -t nfs4
<hangs>

Cheers,
FJP
