NetworkManager unable to set wired dhcp connection (r8169)

[Antonio]

Binary package hint: network-manager

Hi,

I'm running ubuntu intrepid ibex (8.10) on a Dell Vostro 1310 laptop. Networkmanager is unable to setup my wired connection via dhcp (this is a regression since with ubuntu 8.04 I had no problem with NM). NM has no problem with profiles with fixed ip address. Let me explain the problem in detail.

I have two wired profiles in NewtworkManager: "Galileo2" with a fixed ip (work), and "Fastweb cavo" with dhcp (home).

When I boot at home (dhcp), NM set the Galileo2 profile by default. At this point, if I switch to the dhcp profile, the applet says I'm connected to "Fastweb cavo" but I cannot reach Internet. The NM log of this situation is reported in the first attachment.

Furthermore the card at this point is "blocked" and I cannot connect even if I manually type "sudo dhclient eth0" in a terminal. The dhclient output is reported in the second attachment.

*I have to reboot be be able to connect to internet again!* This seems to indicate some bad interaction with the kernel too.

On the other and, if I boot AND do not touch the NM applet, and manually set the eth0 connection with "sudo dhclient eth0" I'm able to connect to Internet regularly. The NM log and the dhclient output in this case is reported respectively in third and fourth attachment.

The used kernel is:
----
  $ uname -r
  2.6.27-9-generic
----

And the ethernet card is
----
lspci -vv

The same problem still exist in jaunty beta. No connection with dhcp via NetworkManager. I have to stop NetworkManager from starting at boot and manually type dhclient to connect.
