Mostly after resume from hibernate the network would not started.
A "sudo service network-manager restart" solve the problem.

sudo lshw -C network

After resume the status is disabled.

The workaround, a file called "unload_modules" in /etc/pm/config.d, with the following value "SUSPEND_MODULES="$SUSPEND_MODULES tg3"" seems sometimes to work.
Without the workaround almost every restart did not start the net, with the WA the network starts mostly but not always.
