I didn't have a problem with 2.6.34 but with 2.6.35-rc1 while obtaing IP
address with dhcpcd it bails out with reason 3 and gets timed out. I've
tried to increase timeout to 100 but the result is the same. I can't
apply this patches because base is somewhat different, as I can see the
first patch is already applied but the second one isn't. Any
suggestions ? Thanks. In the meantime I will try to get some more debug
information.
