Title:
  Ubuntu 12.04 fails to boot after kernel update on T400

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  Hi,

  I just performed a > 150 MB upgrade to 3.2.0.27 with my Thinkpad T400
  and after reboot Ubuntu stopped working: I do get the grub screen but
  after choosing "Ubuntu, with Linux 3.2.0-27-generic" a black screen
  with blinking cursor appears and stays. After that, I can only
  shutdown the system with the power button. I have a second OS to
  choose from in grub which is Windows Vista but booting fails as well.

  Please, any help is greatly appreciated. (Wished I had not done the
  last backup a week ago...)

  WORKAROUND: acpi=off mode
