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:
