Title:
  Unable to boot 12.04 without 'noapic' flag enabled in GRUB

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Since Ubuntu 11.04 my Thinkpad L520 i7 has required the 'noapic' boot
  flag to be set in order to boot successfully. When I first upgraded to
  12.04 on 2011-12-13 this flag was not required to boot into 12.04. But
  an update sometime in January 2012 has caused a regression somewhere
  and now the 'noapic' flag is again required.

  This is quite frustraiting and will mean any new users who don't know
  anything about boot flags will be unable to install Ubuntu on their
  laptops.

  Also note, I also suffered from another bug which broke my primary laptop display on boot. But that has now been fixed in an upstream kernel:
