Public bug reported:
My BCM43602 has a 50/50 chance during boot of ever becoming "ready" and
pulling an IP address. The problem seems to be this "link is not ready"
and "already exists" loop. The log I sent was one of the cases where
things eventually worked. If I get unlucky, it simply repeats the
"already exists" / "not ready" loop indefinitely.
I get a similar situation when suspending/resuming. I've already pulled
the firmware and stuck it under /lib (see dmesg output for version).
