Aha! See, when you actually post *details*, we can start to make some
progress.
An IP address in the 169.254.x.y network is self-assigned by an interface
when it wants to get a DHCP address, but is unable to get a response from
a DHCP server.
So, you have two things going on here:
* The interface is configured to try DHCP.
* The DHCP client is not getting a response.
Other people may be able to offer additional insights. This isn't a
problem I've experienced first-hand. I only know about it from others
on this mailing list.
