Title:
  Setting up mdadm (3.2.5-5ubuntu3) freezes at Found kernel: when
  upgrading from Saucy to Trusty

Status in “mdadm” package in Ubuntu:
  New

Bug description:
  I'm unable to upgrade my Dell PowerEdge T105 from Saucy to Trusty
  because madm freezes during the update grub process during setup. This
  system was originally installed in April of 2009 with Hardy 8.04 and
  has successfully upgraded from revision to revision since then. This
  is the first time madm has failed to upgrade.

  Yesterday evening I ran do-release-upgrade -d and it froze at:

  It sat there for about half an hour so I canceled the do-release-upgrade and tried to recover with the usual steps after cleaning out some stale kernels:

  At this point mdadm setup still just sits forever. If I hit Ctrl-C:
