crash on suspend with up to date kernel

[Stan Schymanski]

OK I think I found a workaround the suspend problem, in case anyone else
(or myself) runs into it ever again:
https://wiki.debian.org/Suspend#Help_on_software_suspend
The follwoing command "unmasks", i.e. activates all energy saving states:
sudo systemctl unmask sleep.target suspend.target hibernate.target
hybrid-sleep.target
Technically, if they are masked, it should do nothing rather than log me
out, but at least unmasking solved that problem (for now).

Cheers
Stan
