There is now a specific spin-off from the closed https://bugs.debian.org/780956 (laptop-mode-tools hooks not triggerd) in the udev binary package: (reassing to src:systemd did not succeed)
To ensure packages have a reliable resume event hook available, udev may echo 0 > /sys/power/pm_async, or some device blacklist may be needed (in the kernel?) to disable async pm?. https://bugs.debian.org/783638 (original reporters may subscribe) The relevant "trigger on resume" mechanism from udev seems to be: ACTION=="add|remove", SUBSYSTEM=="machinecheck", RUN+="lmt-udev auto force" -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
