Title:
  do-release-upgrade from Ubuntu 12.04 on Pentium-M fails, breaks system
  without any warning (This kernel does not support a non-PAE CPU)

Status in Ubuntu Release Upgrader:
  New
Status in “linux” package in Ubuntu:
  Invalid
Status in “ubuntu-release-upgrader” package in Ubuntu:
  Fix Released

Bug description:
  Attempting to upgrade from Precise with a non-PAE kernel will result
  in a failed upgrade. do-release-upgrade should check whether the user
  is using a non-PAE kernel and refuse to run, rather than upgrading to
  a broken system with no installed kernel.

  After downloading 1.5GB+ of data and over 1000 new packages, the
  upgrade will eventually report failure. Looking through the logs there
  is no kernel installed because of the error "This kernel does not
