Hello,

I'm sorry to bother again but since the previous debug aids didn't go anywhere
I'm here to ask again if there is a command, a debug parameter, something that
could tell me the cause of the last system wake up.

I'm aware that in Windows there is the command "powercfg -lastwake", I need
something similar for linux, since this issue is linux specific (I can't
reproduce it in Windows).

Thank you,
