Another workaround is blacklisting the 'rpcsec_gss_krb5' kernel module (in /etc/modprobe.d/blacklist.conf) -
# Blacklist rpcsec_gss_krb5 kernel module; needed for quick NFSv4 mounts, ref. bug https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1270445 blacklist rpcsec_gss_krb5
But obviously the NFS subsystem should not be attempting to load this at all if the system isn't using Kerberos (i.e, no Kerberos keytabs or krb5.conf files)
