Title:
  12.04 isn't cleanly unmounted

Status in “upstart” package in Ubuntu:
  Confirmed

Bug description:
  Noticed this when the boot-time took too long. Every reboot the
  journal must recover the root file system (i have the /home-filesystem
  on a second partition). I saw this in dmesg (not always the same but
  about, and this is always there at every boot):

  [ 9.252087] EXT3-fs (sda1): recovery required on readonly filesystem
  [ 9.252091] EXT3-fs (sda1): write access will be enabled during recovery
  [ 10.928126] kjournald starting. Commit interval 5 seconds
  [ 10.928181] EXT3-fs (sda1): orphan cleanup on readonly fs
  [ 10.928188] ext3_orphan_cleanup: deleting unreferenced inode 338285
  [ 10.928222] ext3_orphan_cleanup: deleting unreferenced inode 337758

  [ 10.936544] ext3_orphan_cleanup: deleting unreferenced inode 1622017
  [ 10.936559] EXT3-fs (sda1): 5 orphan inodes deleted
  [ 10.936562] EXT3-fs (sda1): recovery complete
  [ 11.017444] EXT3-fs (sda1): mounted filesystem with ordered data mode
  [ 31.210636] Adding 3903788k swap on /dev/sda2. Priority:-1 extents:1 across:3903788k
  [ 32.044232] EXT3-fs (sda1): using internal journal

  I have tried much of the workarounds covering dbus bugs or network-
  manager bugs for example
  https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/740390 to no
  success. My system is a stock ubuntu 12.04 with some PPA-packages but
  not system ones. I've no slight idea what happens.
