I have been struggling to solve a problem with a system that
unexpectedly wakes up (from an S5 state).
I have searched the log files to no avail. Mr Google reveals
others will the same problem, but no meaningful solutions as
far as I can tell.
Even when I intentionally wake the system from S5 (via WOL for
example) I am unable to find that event reflected anywhere in
the logs. Booting with acpi.debug_layer=0xffffffff and
acpi.debug_level=0x2 didn't seem to help either.
It seems to me that we need a better diagnostic tool for
tracing the source of wake events; something akin to the
Windows powercfg -lastwake command.
