Does /lib/systemd/systemd-sleep hibernate
work?

What does
cat /sys/power/disk
cat /sys/power/state
say?

The systemd-sleep binary does nothing fancy, as you can see at [1]
So if that command fails, but "echo disk > /sys/power/state" isn't, then
I'm a bit at a loss here.

Do you have a /etc/systemd/sleep.conf or  /etc/systemd/sleep.conf.d/* files?
