Title:
  Gutsy: cryptsetup fails for encrypted rootfs on slow devices (USB)

Status in “cryptsetup” package in Ubuntu:
  Fix Released
Status in “cryptsetup” package in Debian:
  Fix Released

Bug description:
  Binary package hint: cryptsetup

  This bug is *not* a duplicate of bug #85460

  cryptsetup fails for encrypted rootfs on a device that is slow to come
  up (i.e. an external USB HD).  The "udevsettle" solution proposed in
  bug #85460 does not help.

  I have patched /usr/share/initramfs-tools/scripts/local-top/cryptroot
  by integrating into it the same kind of "waiting loop" that already
  exists for a non-encrypted rootfs, in /usr/share/initramfs-
  tools/scripts/local .

  This patch to /usr/share/initramfs-tools/scripts/local-top/cryptroot
  solves the issue and perfectly does the trick. Please consider
  integrating this fix.
