Title:
  NFS Lockups with 13.04 clients to 12.04.03 server

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After a recent upgrade on my clients to Ubuntu 13.04 latest and Ubuntu
  12.04.03 on the server, NFS4 clients began locking up with the errors
  below.  Processes accessing NFS would hang up and lock, and could not
  be killed or adjusted.  NFSv3 on the same server and client has been
  working fine.

  NFS4 was configured with clean defaults, no special options set.  No
  log entries corresponding with the problem were seen on the nfs
  server.
