Title:
  Kerberised NFSv4 stops working after upgrade to 13.10: "RPC: AUTH_GSS
  upcall timed out"

Status in “nfs-utils” package in Ubuntu:
  Confirmed

Bug description:
  Configuration:

  Ubuntu 13.10 client, mounting NFS directories from FreeBSD server.

  Only NFSv4 is used. Authentication is done using the "krb5p" method.
  Relevant line /etc/fstab:

  lion:/export/shared/videos /lion/videos nfs4 sec=krb5p 0 2

  There are a few more of the same, mounting other directories.

  After upgrading from the previous version to 13.10, the mounts does
  not work anymore. Trying to mount manually using: "mount /lion/videos"
  causes the mount command to hang. After terminating the mount command
  (Control-C) the syslog displays the following:

  Nov  4 21:57:13 tiger kernel: [  463.976830] RPC: AUTH_GSS upcall timed out.
  Nov  4 21:57:13 tiger kernel: [  463.976830] Please check user daemon is running.
  Nov  4 21:57:13 tiger kernel: [  463.976960] NFS: nfs4_discover_server_trunking unhandled error -512. Exiting with error EIO

  The gssd daemon is running:

  elias at tiger:~$ ps -ef | grep gss
  root      4998  3035  0 22:03 ?        00:00:00 /usr/sbin/rpc.svcgssd -vvv
