Title:
  fsck progress counter stalls, plymouthd eats cpu

Status in “plymouth” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: plymouth

  PROBLEM

  When a disk check is performed, the progress stalls somewhere around
  70% and will then take a very long time finishing the remaining
  percent (in my case, around an hour).

  WORKAOUNDS

  1. Removing "quiet" and "splash" from the kernel boot line

  3. When the progress has stalled, switch away from the splash screen using the left arrowkey (presumably any arrowkey works).
  This could speed up the boot process to ~1 minute instead.

  OBSERVATIONS

  The fsck message "somethingsomething non-contiguous
  somethingsomething" Which I assume indicates the end of the fsck, is
  printed in the Virtual Terminal (Not-plymouth) at around 70% + ~10-20
  seconds.

  Disk activity is null from this point on (presumed end of fsck above).

  Bootchart crashes if trying to catch the whole boot at once.

  TEST CASE:

  (sudo aptitude install bootchart)
  sudo touch /forcefsck && sudo reboot
