So it's highly likely that the 64 bit addresses used for specific PM
registers are wrong in the FADT, where as they are correct in the 32 bit
addresses.

The FADT supports old 32 bit legacy addressing for PM registers and 64
bit addressing too.  Unfortunately sometimes the firmware sets the 64
bit versions incorrectly and the kernel is now using these in preference
to the 32 bit variant, hence the issue.

Title:
  [HP Compaq 6715s] Updating kernel renders system unbootable

Status in linux package in Ubuntu:
  Triaged

Bug description:
  To reproduce (on this hardware)

  1) Install 14.04.3 LTS (Ubuntu or XUbuntu)
  2) Install updates
  3) Reboot

  The kernel used after update is 3.19.0-42. Booting with the kernel
  that came with the install image (3.19.0-25) works fine.

  This computer is a HP Compaq 6715s. I have looked at HPs support pages
  for BIOS updates for this model but none was available.
