Title:
  mdadm fails to activate raid partitions in 10.04
  (add_mountroot_fail_hook: not found)

Status in initramfs-tools package in Ubuntu:
  Expired

Bug description:
  Binary package hint: initramfs-tools

  After upgrading a system with root on a raid partition from 9.04 to
  10.04, initramfs fails to mount root in 2.6.32-21-generic.

  When booting with an old kernel and initramfs (2.6.28-17), it works.

  I get a message about add_mountroot_fail_hook: not found.
  And indeed, such symbol is defined in scripts/functions in the old initramfs, but not in the new one.

  Removing and re-installing the mdadm package, and rebuilding the new
  initramfs did not help.

  However, if I specify the root fs as /dev/md4 (rather than with its
  UUID), and then do mdadm -A --scan on the initramfs prompt, everything
  works fine.
