No joy here either. 2.6.29-rc8 + this patch shows the same misbehaviour
as 2.6.29-rc7 had. Here's a minicom log of an attempted boot:

(kernel messages)

r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded

Bringing up interface eth0: RTNETLINK answers: Cannot assign requested address

May I suggest that 6709fe9a27e43a4931938fe0d7f2cc5edef31386 is reverted
until this regression is debugged and fixed?
