Thanks for looking into this! This is two years back, but I believe I filed the bug report after an upgrade. In the meantime, I have updated the box to 12.04 LTS. Will see if the problem persits (and how if so) and send updates, here.

I can still get an IP manually through "sudo dhclient eth0". Strange thing is that "Auto eth0" was gone already 2010-05-08, and I had to manually re-add a DHCP wired connection. But as of now, even this does not help. I have attached a recent copy of the daemon.log.
