Could you please post your /etc/network/interfaces file ?

I suspect that you have a interface listed there as 'auto' that is not
plugged in.  If that is the case, the correct solution for you is to
remove that line or comment it out.  To be clear, I suspect you have
something like:
  auto eth0
  iface eth0 inet dhcp

but your eth0 is not plugged in.

Title:
  failsafe.conf's 30 second time out is too low

Status in “upstart” package in Ubuntu:
  Fix Released

Bug description:
  as far as I can understand, the 30 second sleep in failsafe.conf means
  that /etc/init/rc-sysinit.conf will start within at most 30 seconds of
  'filesystem' and 'ifup lo' having occurred.

  I think that is really to small a number.   You're only safeguarding
  against the case where a user had an entry in /etc/network/interfaces
  that where the device was removed or is not connected.  Thats a very
  rare case.  Increasing the timeout to 60 seconds would make it less
  likely to have a false positive and have rc-sysinit start early.  (Ie,
  the case where a dhcp took 35 seconds).

  The user will only be punished by waiting an additional 30 seconds in
  the case that they have a  misconfigured or out of date
  /etc/network/interfaces.
