[Bug 1438301] [NEW] desktop machine suspends with systemd after ~3 minutes, does NOT suspend with upstart

[Colin Ian King]

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.
