I have found this workaround on the forum http://ubuntuforums.org/showthread.php?p=11403944
Just type this in a root command prompt
cd /etc/init.d && update-rc.d -f umountnfs.sh remove && update-rc.d umountnfs.sh start 19 0 6 .
It worked for me. It is actually moving the order of umountnfs to call it before sendsigs so the nfs share are unmounted before killing all the remaining process. It's not a bug correction, but it works.
