Hi,
Recently I wanted to implement TV power off function as a part of XBMC shutdown (suspend) procedure.
So I've added new scrip in /etc/pm/sleep.d which is first checking "TV On" sensor (by connecting over network to TV status sensor) and if TV is on, it sends power off IR signal to TV.
I've tested the script alone - it worked fine. When I place the script in /etc/pm/sleep.d and then used command:
pm-suspend
Computer is suspended and script worked fine(TV got powered off before suspend).
However when I use suspend option of XBMC or let XBMC to suspend due to inactivity timeout, it doesn't work - script is executed, however I've noticed that it can't query sensor, because network is already down.
Do you have any ideas why (and how) XBMC disables network, when suspend option is selected in XBMC?
Piotr

XBMC does not disable the network, the OS is doing that. Xbmc just calls suspend.

What function/command XBMC uses to suspend? Because if I use pm-suspend command from commandline, it works fine - I mean it goes thorough suspend scripts and network is disabled by one of the scripts. In XBMC it seems that network is disabled immediately:-(

Ive also noticed this; youre not crazy.
First lines of : pm-suspend log an 'ip link show'.
When I execute pm-suspend script eth0 is UP.
When I execute suspend via xbmc eth0 is DOWN.
This confirms that something else is happening between the xbmc suspend function and pm-suspend.
EDIT:
xbmc.log:

Just a quick update on this, XBMCbuntu does come with and use NetworkManager for suspend specifically requesting a lan disconnect prior to suspsend..
May 29 23:44:25 localhost NetworkManager[1085]: <info> sleep requested (sleeping: no enabled: yes)
May 29 23:44:25 localhost NetworkManager[1085]: <info> sleeping or disabling...

It is possible this could be better implemented in the XBMCbuntu Ubuntu setup.
