To bring more to the discsussion regarding uses of events at both wakeup and suspends.
On suspend apps can close sockets and signal disconnects properly to servers (even if the server in itself probably should handle a wrong disconnect it's nice to support it nicely).
Hmmm... I know that my common suspend use case involves closing the
lid and putting my laptop in my backpack, so I want suspend to happen
as quickly and reliably as possible, and waiting for network
connections to cleanly shut down strikes me as creating another set of
failure points. I would rather rely on userspace network apps cleaning
up after themselves at resume if needed.
On resume sockets could get reopened. In XBMC, LIRC comes to mind as a perfect candidate, it tends to need reinitiate and we want suspend to behave transparently as shutdown, so resume needs to look like a startup so we rescan and such.

I think doing this as pm-utils level is the wrong layer. Richard. -------------- next part -------------- An HTML attachment was scrubbed...
