Systemd in Bionic/Xenial does not support AllowSuspend=, etc., just SuspendMode=, HibernateMode=, HybridSleepMode= and SuspendState=, HibernateState=, HybridSleepState=.
Setting *Mode=hibernate would probably work. If Bionic and Xenial should be fixed, too, could you please confirm that?
@arighi, thanks for the info.
Is the deadlock observed on Bionic/Xenial, too?
