It may help... I hope someone can solve this... I booted my notebook with a Ubuntu 9.04 netbook usb drive (because the default live-CD doesn't work with my graphics card right-out-of-the- box).
I booted with network cable disconnected. Here's the syslog: May 28 15:09:38 ubuntu kernel: [ 246.640044] eth0: auto-negotiating...
