Public bug reported:

On the client:

#mount -t nfs -o vers=3,nfsvers=3,udp,insecure -v 192.168.4.1:/data/media/mythtv temp/
mount.nfs: timeout set for Thu Feb 23 10:52:15 2012
mount.nfs: trying text-based options 'vers=3,nfsvers=3,udp,insecure,addr=192.168.4.1'
mount.nfs: prog 100003, trying vers=3, prot=17
mount.nfs: trying 192.168.4.1 prog 100003 vers 3 prot UDP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 192.168.4.1 prog 100005 vers 3 prot UDP port 44107
mount.nfs: portmap query failed: RPC: Program/version mismatch
mount.nfs: Operation not permitted

On the server:

cat /etc/exports
/data/media/mythtv	*(rw,no_subtree_check,no_root_squash)

If I use NFS4 "it works" but UDP brakes after a while. TCP causes lag
due to the protocol. before the client upgrade this worked. The server
has been running "12.04" for a LONG time now, client updated 1 day ago.
