We have the same problem here - all home dirs are nfs-shares which now don't mount on boot so one cannot login.
In the beginning (after our upgrade) some shares at least mounted, but the last few days none mount.
Server is still running NFS v3 under Hardy, clients are newly upgraded to Lucid.
Logging in with a local user and issuing mount -a does work after the system is started.
