Title:
  initramfs fails to mount LUKS root partition after upgrade to Quantal

Status in initramfs-tools package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to 12.10 via "do-release-upgrade", I am no more able
  to boot. Previously I was able to boot with the same setup since
  Ubuntu 10.10.

  My /, /home, /var and /mnt/media partitions are LUKS encrypted LVs on top of RAID10,RAID1 md arrays and accessed via a key-file on a usb-stick.
  /boot is on an unencrypted md (md0).

  What I would have expected is cryptsetup mapping the encrypted volumes, mounting them and normal boot of the system.
  Actually cryptroot unlocks the key slot of the root filesystem (cryptsetup: cryptroot setup successfully) but it gets stuck on waiting for the root filesystem.

  WORKAROUND:
  Boot in recovery mode. Wait for the timeout for the root fs to finish. In the recovery menu select "root" to access the root shell.
  Eventually the root filesystem is mounted after the failure hooks and I am able to boot by typing:

  # mount / -o remount,rw
  # mount /boot
  # mount /mnt/keydev
  # cryptsetup -d /mnt/keydev/keys/darkgoo/data-media luksOpen /dev/mapper/data-media data-media_crypt
  # cryptsetup -d /mnt/keydev/keys/darkgoo/data-homes luksOpen /dev/mapper/data-homes data-homes_crypt
  # cryptsetup -d /mnt/keydev/keys/darkgoo/data-var luksOpen /dev/mapper/data-var data-var_crypt
  # mount /home
  # mount /var
  # mount /media
  # exit

  Select menu item "resume".
  The system now boots succesfully.

  #lsb_release -rd
