Title:
  [Lenovo b485]: Can't install precise 12.04.2 or 12.04.3 from live
  image or via PXE

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Problem,

  I'm currently unable to install 12.04.2 via PXE or live cd image.

  When trying to install via PXE the machine will hang with the
  following kernel messages showing:

  [0.004205] [Firmware Info]: CPU: Re-enabling disabled Toplogy Extensions Support
  [0.004254] CPU: Physical Processor ID: -
  [0.004293] CPU: Processor Core ID: 0
  [0.004322] mce: CPU supports 7 MCE banks
  p0.006443] ACPI: Core revision 20120320

  Whey trying to install via Live CD or Live USB I receive the following message:
  "If you're seeing this the installation has failed", from this point I can select to boot into single user mode, or an automated install.
  Selecting either causes the machine to hang with a cursor in the top left corner.

  Reproducable?: Yes
  I've reset all BIOS settings to the default values.

  In 12.04.1 the system will attempt to boot from the key/CD after
  selecting "Install Ubuntu" and proceed (trackpad is disabled and
  Ubuntu Desktop never loads"

  When trying to boot raring live image, the machine simply reboots
  never displaying a Grub Menu option.

  I have confirmed that the live images I was using are working with
  other machines without issue.
