I have another laptop that have no problems with network-manager, I
have all interfaces commentented except for "lo".

>From ubuntu's wiki: "NetworkManager doesn't manage interfaces with
manual configuration defined in /etc/network/interfaces. To get n-m to
manage all the interfaces properly, backup /etc/network/interfaces and
remove all wired/wireless interfaces that you want to be managed by
n-m"

I really think it's a bug.. any suggestion on what information could
be useful send?
