[solved] uswsusp: how to suspend to ram without killing network

Hi guys.
On my acer aspire one (D150) I use uswsusp instead of kernel mode. The laptop goes to sleep and restores in a sleep second, which is fantastic.
However, when I run s2ram from the shell it goes to sleep maintaing the wifi connection so that when I open the lid I am up and running instantaneously. When I use pm-utils, on the other hand, somehow the network gets shutdown so at resume I need to associate via DHCP again.

Does anyone know how to overcome this? I want the sleep behaviour to be the one of s2ram only, namely wifi not disconnected.

Thanks

Alright, I figured it out.

gg@Majorana:~$ cat /etc/pm/config.d/config 
HOOK_BLACKLIST="55NetworkManager"
SLEEP_MODULE="uswsusp"

The Networkmanager hook had to be blacklisted. Now it works.
