So, now i try to formulate a new short bug description with all facts i know at the moment :
Since kernel version 4.4.0-42 (offical repo for 16.04.1) the boot process crashed when there are at least two nfsv4 entries to the same nfs-server in /etc/fstab With only one share entry in the /etc/fstab the boot prozess do not crash.
