Hi,
i tried 2.6.26-dostoevsky.1 kernel and everything works like clockwork.
The only steps I did are the following
# sudo /etc/init.d/nfslock restart
audit_log_user_command(): Connection refused

Starting NFS statd: [ OK ]
# sudo /etc/init.d/nfsrestart
sudo: /etc/init.d/nfsrestart: command not found
# sudo /etc/init.d/nfs restart
