Recently flipped to Ubuntu 11.10 on a Dell 4300 (Intel). Getting IP address and no issues (ping/surf) but Wireshark unable to detect eth0 interface. I see references in forums to blacklist tulip but looks like I am running dmfe. Not sure if the blacklist is required and where to go from here. Maybe Driver update? Got a little lost looking in that area.
Some h/w details below (IP/MAC/HOSTNAME removed)
