--- Comment #4 from Elizabeth <elizabethx.de.la.torre.mena at intel.com> ---
I did as follow:

1 - Send platform to freeze state by doing:
     # echo freeze > /sys/power/state
2 - Press power button. It returns properly, no hangs on dmesg, no errors with
PM:
     gfx at gfx-desktop:~$ dmesg | grep -i pm:
         [   57.123872] PM: suspend entry (s2idle)
         [   57.123875] PM: Syncing filesystems ...
         [  160.341653] PM: suspend exit
     gfx at gfx-desktop:~$

Though if I press any key in the keyboard the platform won't wake up, only when
the power button is pressed. If freeze state is supposed to work that way, then
this bug can be closed.
