pm-hibernate with BLFS 7.7 works well, but no longer turns off my computer.
I've checked my "Power management and ACPI options --->" and they appear
consistent with those I used with BLFS 7.6. As an experiment, I dropped my
BLFS 7.6 3.16.2 kernel into /boot and pm-hibernate turns the computer off.
As a result, I assume there's a problem with the 3.19 kernel. Is that
logical? Is there a /etc/pm/sleep.d hook I should use to fix the problem.
Using the old kernel with BLFS 7.7 isn't a big problem, but I'd like to be
consistent and current if it's a hook I'm missing.
I can't help with pm-hibernate, but pm-suspend works ok for me.
I think you are saying that it shuts down when you hibernate, but
does not power off. If so, does a regular shutdown turn it off ?
Also, 3.16.2 came out more than 6 months, and three releases, ago.
Change in the kernel is vast, it could be that one of the previous
two releases disagrees with your hardware.
A machine with intel graphics ?
Googling for
lkml 2015 shutdown does not power off
(to restrict it to very recent posts - my initial attempt for 2014
found nothing that looked relevant) but did drop into a thread from
February : https://lkml.org/lkml/2015/2/25/491
That is also in
http://lists.freedesktop.org/archives/intel-gfx/2015-February/
but I could not work out what the current status is.
Google found a patch at
http://patchwork.lespiau.name/patch/2622/ - does that help ?
If it does you should probably talk to the submitter to establish
what the current position is (it might already be in 4.0-rc, and
either in a 3.19.x release, or on its way to 3.19.y, or there may be
issues).

Thank you, the patch worked. In weighing the possibility of a kernel
problem versus an error on my part, I assumed it was my error. That
logic normally serves me well. I should have investigated the kernel
end more but appreciate your finding the patch. I'll follow your
suggestion and contact the patch submitter.
