Bug description:
  Ubuntu fails to properly boot on Macbook Air 2013 6,1

  Ubuntu fails to boot the 13.10 live image from usb without specifying
  acpi-off as a boot parameter.

  After installation is complete the boot process hangs at a purple
  screen. Booting into recovery mode shows that the process stops at the
  following:

  smpboot: Booting Node 0, #1

  I've tried 12.04.2, 13.04, and 13.10. I've also tried booting with
  kernel ver 3.9.8-030908-generic and the result is the same.
