I bisected to this ... as it breaks nfs3-only servers in 6.3.
I.e. /etc/nfs.conf containing:
[nfsd]
vers4=no

The client sees:
  mount("10.0.2.15:/tmp", "/mnt", "nfs", 0, "vers=4.2,addr=10.0.2.15,clientad"...) = -1 EIO (Input/output error)
  write(2, "mount.nfs: mount system call fai"..., 45
  mount.nfs: mount system call failed for /mnt

And the kernel says:
  nfs4_discover_server_trunking unhandled error -5. Exiting with error EIO
