This looks like it starts with the ethernet link up, and goes down
before udhcpc is started, then after several minutes it goes up again,
and even then udhcpc fails -- perhaps the link has gone down a second
time?

This could be anything from a faulty driver to a hardware problem to a
cable problem.
