Steps to reproduce.
1) install fresh copy of Vivid
2) apt-get -yqq install mysql-server libmysqlclient-dev
3) reboot + system hangs forever (because mysql can't seem to be stopped in all cases by systemd)
4) In another shell - mysqladmin shutdown - allows reboot continues
5) Also - service mysql stop - hangs forever, so only way to consistently stop mysql is via - mysqladmin shutdown
This situation only occurs after several mysql restarts + this situation seems to occur on every Vivid install I've done.
Down leveling to Utopic is how I've had to fix this.
