Can you attach the content of /var/log/upstart as well as your
/etc/network/interfaces?

Title:
  ifupdown not working when multiple interfaces

Status in “ifupdown” package in Ubuntu:
  New

Bug description:
  Ubuntu Server 12.04
  ifup hangs when trying to start interface (only when using dhclient)
  ifdown is complaining that interfaces is not in '/run/network/ifstate', and so refusing to stop it.
  BUT worse ifdown eth2 will shutdown eth0, and so I lose connection over eth0 SSH.
  After reboot, server cannot setup network.

  Problem lies when ifup is forking to dhclient and it gets also messed
  up with is '/run/network' files. When using only one interface
  everything works fine but when two or more interfaces are setup it
  becomes buggy, for now I replaces ifup with ifconfig in
  '/etc/init/networking.conf'.....
