Just a note: in /etc/default/halt I already had:
Having said that, great mystery: I touched nothing, and poweroff works

1/ Closed everything running (as I usually do before switching off the
computer) then run from a terminal (in gnome):
sudo halt -p
I had forgotten to unplug two external usb disks, the system went down
and tried to reboot, but it couldn't for these are not system disks.
This was kind of expected after these later days behaviour and having
made that mistake with respect to the external disks.
2/ Unplug the disks. Press the power button > complete power off, first
time from Monday. Surprise.
3/ Boot the machine from the same button. Log
in, open a terminal,
sudo halt -p
This also resulted in complete power off. Good.
4/ As 3/ but writing:
Also resulted in complete power off. Excellent.
5/ Repeated 3/ and 4/ after having plugged, then unplugged the external
disks. Again, both resulted in complete poweroff. Amazing.
6/ Boot the machine, logging in, work for a while and this time try to
power off from the gnome menu. To my complete astonishment, it did work...
Now, may the problem be related with something I do during my normal
work in the day (normally I switch on the laptop in the morning then off
in the evening) ? I don't think so, but I will now this evening, I suppose.
Thanks again !

Yes, systemd is probably the cause, it replaced pm acpi by its own
terminology, disregarding the legacy convention.
Yes, systemd will happily break existing ACPI PM setups without any
The systemd point of view is that any breakage is caused by other
packages failing to detect that systemd is installed. Their
interpretation of "not breaking unrelated
software" is that any software
they break should detect that systemd is present and disable itself.
This systemd breakage is intentional, and any errors you experience is
entirely acpi-support's fault if you have configured it in such a way
that the disabling logic fails.
if nothing else helps, replace systemd with systemd-shim emulation
(maybe also switching back to sysvinit).
This won't help. systemd-shim needs systemd to provide
e.g. systemd-logind and that's where the breakage is. You can disable
the systemd interference in this case by setting
BTW, I have given up reporting systemd bugs. What's the point? The
Debian maintainers have inherited the upstream point-of-view: "If
something broke when you installed systemd, then that is someone else's
fault for not adapting properly to systemd". And "broken by design is a
