Public bug reported:
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.
