Title:
  Ubuntu 13.10 64bit livecd won't boot unless acpi=off on Dell Optiplex
  745

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am booting  live cd of Ubuntu 13.10 Desktop 64bit but it ends with kernel panic because of some issues with acpi. I tried the following:
   - when I provide parameter acpi=off it boots ok.
   - when I provide acpi=ht (or no parameter) it generates kernel panic (see the screenshot in attachment).

  Moreover I can run 32bit version of Mint 15 with no acpi issues which
  suggests that only 64bit version is affected.

  There is attachment with two subdirectories: one contains data from
  Ubuntu 13.10 64 bits livecd taken with acpi=off and the second taken
  from 32bit version Mint 15.
