Title:
  [14.04] Boot stuck in "Starting configuring network devices" after
  upgrade

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  One of these upgrades yesterday resulted in an unbootable system:

  2015-01-19 20:32:45 upgrade libc-dev-bin:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5
  2015-01-19 20:32:47 upgrade libc6-dev:amd64 2.19-0ubuntu6.4 2.19-0ubuntu6.5

  2015-01-19 20:33:10 upgrade libcgmanager0:i386 0.24-0ubuntu7.1 0.24-0ubuntu7.2
  2015-01-19 20:33:11 upgrade libcgmanager0:amd64 0.24-0ubuntu7.1 0.24-0ubuntu7.2
  2015-01-19 20:33:12 upgrade linux-firmware:all 1.127.10 1.127.11

  I'm unable to debug this any further because the desktop system is in
  another part of the country. I got the error report by a phone call by
  a non-technical non-English-speaking user, on whos machine I installed
  Kubuntu. After a while I got him to boot into the recovery prompt and
  enable me SSH access so I could downgrade these packages. After
  downgrading the system restarted well and came up.

  The user reported that the boot process was stuck at a "Starting
  configuring network connections" prompt or something. I'm not entirely
  sure, but I might have heard him muttering something about some cgroup
  messages.

  Anyway I still have SSH access, but I can't do on-site debugging until
  February 7 or restart via SSH and risk having to contact the user to
  recover from a broken boot.
