Public bug reported:
For reasons I cannot fathom, my development server goes into deep
suspend after ~3 minutes after startup with systemd, however, if I boot
with upstart it does not. This happens everytime I boot with systemd,
the machine just goes into a deep suspend without me requesting it.
I enabled "debug"; attached is a gzip'd syslog showing the activity -
look at the end of the log, it goes into deep suspend. No idea why.
acpi_listen is showing some curious audio plug/unplug events that seem
to occur on this development box, so maybe these are being
misinterpreted as suspend events.
$ acpi_listen
jack/headphone HEADPHONE plug
jack/headphone HEADPHONE unplug
jack/headphone HEADPHONE plug
jack/headphone HEADPHONE unplug
jack/headphone HEADPHONE plug
jack/headphone HEADPHONE unplug
..but I am not seeing any other ACPI related events that could be
triggering a suspend request from acpi_listen.
