Is there any possibility that one of the steps of the bisection was
wrong?  Could you possibly have accidentally marked a "bad" kernel as
"good"?

Addresses like 169.254.123.251 are RFC 3297 zeroconf link-local
addresses.  I think network manager will assign one of those if it
thinks the DHCP negotiation failed.

It might be informative to compare the network manager and dhclient log
output (maybe in /var/log/daemon.log?) in the good and bad cases.

 - R.
