Duh! I had exactly the same problem this week when I "quickly" set up an 
NFS server on one of my boxes: forgot to add fsid=0 for the NFS4 root. 
Result was the mount hanging on the client and the same errors as Ben 
reported.

It would be great if this configuration problem was detected better.

P.S. /var/lib/nfs/v4recovery on the server was empty in my case.
