<b>Workaround</b> and update that may aid in debugging.

I have learned recently (through extensive testing) that pm-hibernate
works flawlessly!  As a workaround I set KDE to hibernate when the power
button is pressed and not ask for a password on resume.  Now I can press
the power button and the machine "hibernates" which, for some reason,
successfully gets the computer to poweroff instead of just rebooting.

I followed this guide to enable hibernation on KDE in Ubuntu 14.04 LTS:
https://help.ubuntu.com/14.04/ubuntu-help/power-hibernate.html   Don't
forget you have to reboot the machine before the settings take effect,
and I had to set the .pkla file rwx for everybody (i.e., sudo chmod 777
/etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
).  Then it worked great.

The settings for the power button in KDE are in systemsettings -> power
management -> energy saving and systemsettings -> power management ->
advanced settings

Please keep me posted if this bug every gets fixed, but I'm happy to
have found a better workaround than always holding the power button for
5 seconds to force a poweroff.

Title:
  Computer Reboots Instead of Halting

Status in linux package in Ubuntu:
  Triaged

Bug description:
  With Ubuntu 14.04 LTS, everytime I try to shutdown my system reboots instead. I have tried a variety of shutdown methods including:
  sudo init 0
  sudo shutdown -P now
  sudo shutdown now
  sudo shutdown -h now
  sudo shutdown -H now
  sudo shutdown -HP now
  (all previous variants with "now" replaced with "1")
  shutting down via the KDE menu (clicking the menu, clicking 'leave' section, clicking shutdown in the dialog box).

  The system hard shuts down if I hold the power button for 5 seconds.

  I have attached a zip of my entire /var/log directory.
