This bug was fixed in the package mdadm - 3.2.5-5ubuntu1

---------------
mdadm (3.2.5-5ubuntu1) raring; urgency=low

  * Implement plymouth hooks for degraded RAID questions. (LP: #1102499)
  * Merged Intel Matrix Storage initramfs support.
  * Merge from Debian, remaining delta is still the same:
    - Call checks in local-premount to avoid race condition with udev
      and opening a degraded array.
    - debian/initramfs/local-premount: add call wait_for_udev to wait a
      little longer for RAID devices to appear (LP: #942106)
    - d/initramfs/mdadm-functions: Record in /run when boot-degraded
      question has been asked so that it is only asked once
    - pass --test to mdadm to enable result codes for degraded arrays.
    - debian/control: we need udev and util-linux in the right version. We
      also remove the build dependency from quilt and docbook-to-man as both
      are not used in Ubuntus mdadm.
    - debian/initramfs/hook: kept the Ubuntus version for handling the absence
      of active raid arrays in <initramfs>/etc/mdadm/mdadm.conf
    - debian/initramfs/script.local-top.DEBIAN, debian/mdadm-startall,
      debian/mdadm.raid.DEBIAN: removed. udev does its job now instead.
    - debian/mdadm-startall.sgml, debian/mdadm-startall.8: documentation of
      unused startall script
    - debian/mdadm.config, debian/mdadm.postinst - let udev do the handling
      instead. Resolved merge conflict by keeping Ubuntu's version.
    - debian/mdadm.postinst, debian/mdadm.config, initramfs/init-premount:
      boot-degraded enablement; maintain udev starting of RAID devices;
      init-premount hook script for the initramfs, to provide information at
      boot
    - debian/mkconf.in is the older mkconf. Kept the Ubuntu version.
    - debian/rules: Kept Ubuntus version for installing apport hooks, not
      installing un-used startall script.
    - debian/install-rc, check.d/_numbers, check.d/root_on_raid: Ubuntu partman
      installer changes
    - debian/presubj: Dropped this unused bug reporting file. Instead use
      source_mdadm.py act as an apport hook for bug handling.
    - d/p/debian-changes-3.1.4-1+8efb9d1ubuntu4: mdadm udev rule
      incrementally adds mdadm member when detected. Starting such an
      array in degraded mode is possible by mdadm -IRs. Using mdadm
      -ARs without stopping the array first does nothing when no
      mdarray-unassociated device is available. Using mdadm -IRs to
      start a previously partially assembled array through incremental
      mode. Keeping the mdadm -ARs for assembling arrays which were for
      some reason not assembled through incremental mode (i.e through
      mdadm's udev rule).
    - udev-md-raid.rules to not auto-start arrays based on detection
      of ddf or isw (imsm) signatures; this conflicts with dmraid usage in
      precise and requires more analysis before it can be enabled in SRU.

  * Merged in Debian:
    - Copy udev rule from /etc/udev/rules.d/ as well as the
      /lib/udev/rules.d/, to allow local administrator to override mdadm
      rules file.

mdadm (3.2.5-5) unstable; urgency=low

  * add (empty) restart and force-reload actions to mdadm-waitidle
    script -- this script is used only when the system needs to be
    shut down or rebooted, there's nothing to start or restart.

mdadm (3.2.5-4+mdmon) experimental; urgency=low

  * fix `/etc/init.d/mdadm-raid status' inverse logic (Closes: #686100)
  * /etc/init.d/mdadm: change RUNDIR to /run instead of /var/run.
    Mdadm itself uses /run internally, we properly depend on initscripts
    version which creates /run, and the initscript itself is started
    after local_fs is processed, so this is merely a no-op, but let's
    do it for consistency.
  * Fix 'enough' function for RAID10, to prevent starting of a RAID10
    array which does not have required minimum of component devices.
    (Closes: #691668).
  * fix segfaults in Detail() - mdadm --detail may segfault if a drive
    has been removed from the array (Closes: #691670)
  * super0: do not override uuid with homehost.  The bug prevented
    re-creating an array with v0.90 superblock with the specified uuid
    when homehost is also specified.  (Closes: #686703)
  * several fixes for mdmon argument processing (Closes: #691671):
    - allow --takeover when original was started with --offroot
    - fix arg parsing.
    - fix arg processing for -a
  * Changes based on a patch by Miquel van Smoorenburg (Closes: #684708):
    - install mdmon in udeb and initramfs, so imsm arrays can work.
      mdadm runs mdmon automatically when needed (currently for imsm
      arrays), and mdmon is required to make such arrays read-write
      (they're read-only by default) so merely presence of mdmon is
      enough to be able to use imsm arrays.
    - /etc/init.d/mdadm start: if a mdmon pidfile is found in /run/mdadm,
      restart mdmon (--takeover --all)
    - /etc/init.d/mdadm stop: link pidfiles of mdmon processes into
      /run/sendsigs.omit.d, and make sure that happens before sendsigs runs.
    - stop mdadm before sendsigs, so that the above code works
    - add script mdadm-waitidle that runs just before reboot/halt.
      For each array that is still running, it sets sync_action to idle,
      and uses mdadm --wait-clean to wait for all arrays to go idle
      (it has a short timeout).

mdadm (3.2.5-3) unstable; urgency=low

  * revert "Drop unused debconf templates" change -- the templates
    are actually being (indirectly) used in debian/mdadm.config
  * fix initramfs-script config name (slipped in the initramfs fixes)

mdadm (3.2.5-2) unstable; urgency=low

  [ Sergey B Kirpichev ]
  * Fix mdadm.lintian-overrides
  * Fix spelling in binaries, fix lintian warnings
    manpage-has-errors-from-man and hyphen-used-as-minus-sign
  * Drop unused debconf templates
  * Implement status option for mdadm-raid init.d script
  * Fix lintian info's conflicts-with-version: Conflicts -> Breaks

  [ Michael Tokarev ]
  * fix spelling mistakes in previous changelog entry
  * some cleanups for checkarray:
   - change --help printing and shorten/simplify the text
   - make --quiet cumulative and stop documenting --real-quiet
   - do not produce help in case of incorrect usage, and exit with 1
  * fixes for initramfs integration (Closes: #644389, #678262, #685161):
   - check INITRDSTART=none early
   - do not explicitly load raid level modules (modprobe/kmod does this)
   - do not collect needed raid levels (we include all modules anyway)
   - load md_mod explicitly since we need to change global parameter

  [ Dmitrijs Ledkovs ]
  * Use dh_installinit with --no-restart-on-upgrade, which will start
    arrays, but will not stop them during upgrade. (Closes: 678971)
  * Copy local administrator's modified udev rules as well as the system
    one. (Closes: #678973)
