On my Dell Inspiron 11z resuming from hibernating and suspend works, except network manager would not reconnect via eth0. WLAN reconnects without any trouble. Gnome nm-applet icon in tray tried to connect, but obviosly does not get IP throu dhcp and stops with the message: "You are now disconnected from auto-eth0". After reboot it connects without problem to the wirde network (eth0). I tried to restart network-manger when problem after resuming occurred, without any success. Additionally  i tried to connect manually via bypassing network manager in configuring /etc/network/interfaces both for dhcp or fixed ip address and restarting   network - again without any success. Only rebooting helps to get a wired connection.
I am using Ubuntu 10.04. I reinstalled Win7 to see, if there is the same problem, which is not.  Wired Network works well after resuming both from suspend and hibernate. (I am on Ubuntu again, dont worry...)
