Nothing freezes in this bug. So your case is different, possibly
related to http://pad.lv/1080701

Title:
  Precise/Raring does not detect proper device
  (/dev/mapper/isw_<something>_Volume0p1) during preseed install

Status in “debian-installer” package in Ubuntu:
  Confirmed
Status in “grub-installer” package in Ubuntu:
  Confirmed
Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  1. Description of the problem:
  When performing a preseed install, on Dell machines using the Intel Matrix RAID controller (BIOS/FW Raid - Intel Corporation Patsburg SATA RAID Controller) the installer fails to find the proper device and prompts where to install grub.
  The installer will just show "/dev/mapper". If you do install to just /dev/mapper it will fail. Instead I have to tell the installer to point to /dev/mapper/isw_<something>_Volume0".

  IMPORTANT: debug files are attached to this bug

  2. Ubuntu release, software version, Release Number and Architecture of the selected components.
  Ubuntu 12.04.2 LTS AMD64 AND Ubuntu Raring

  3. How reproducible is the problem?
  Always using the reported Intel Matrix RAID controller (BIOS/FW Raid).

  4. Steps to Reproduce:
  1. Download ubuntu 12.04.2 alternate cd or Raring:
  http://releases.ubuntu.com/precise/ubuntu-12.04.2-alternate-amd64.iso

  2. Use a preseed file template for automatic installation

  3. Change the kernel boot options to your preseed file as below:
  flags=all-x DEBCONF_DEBUG=5 auto=true priority=critical
  url=http://webserver/server.seed vga=788 initrd=/install/initrd.gz quiet --

   a. Actual Results:
  When you get to the end of the installation, it will ask
  where to install grub to. The installer will just show
  “/dev/mapper”. *Do not install to just /dev/mapper or else it will
  fail. Instead, tell the installer to point to
  /dev/mapper/isw_<something>_Volume0”. * From here, grub should
  install to the correct location and the system should boot.

   b. Expected Results:
  Install the system on the proper boot partition without being prompted by debian-installer.

  5. Known Workaround:
  Install the system manually making sure you select the right device. ie: /dev/mapper/isw_????????_Volume0p1
