Followup-For: Bug #511896

Dear Maintainer,

I see a similar issue when trying to re-install over an all ready
existing Debian Wheezy install.

In my case a full disk encrypted LVM was all ready present.  From a USB
net-install the partitioning step hangs at 39%.  The system is still
responsive and shells work.

A `ps' shows `mdadm' running and not stopping.  Manually running mdadm
from a shell results in an uninterruptible hang of that program.

Scrubbing the the partition table on the hard-disk with the existing
installation (via `dd if=/dev/zero of=/dev/sda bs=1M count=10') allows
the installer and mdadm when next run to complete and things to proceed.

Hope this helps!
