I have experienced this bug today.  Installing ulatencyd renders an
unbootable system (because it causes kernel panic). Uninstalling it
solves the problem.

Bug description:
  After latest kernel update to 3.2.0-29 Ubuntu 12.04 causes kernel
  panic on boot with ulatencyd installed. Removing the ulatencyd solves
  the problem. Attached kernel log.  Seems that this is related to the
  network manager process.
