I suspect you have eth0 dhcp configuration in your
/etc/network/interfaces configuration? Is that correct? Is this
interfaces connected during boot?

If not, dhclient will timeout, and avahi-autoipd will kick in, assigning
a link local IP address. It basically works as designed.

If so, you should fix your /etc/network/interfaces to use something like
ifplugd, to only activate the interface when the interface is actually
connected, remove the eth0 configuration completely if not needed, or
use a tool like NetworkManager, which deals with that properly.
