Re: [Bug 1577113] Re: 50/50 chance for BCM43602 to come up correctly during boot
A recent update has made this work flawlessly on every boot. No idea which
update it was, but we're good now.

50/50 chance for BCM43602 to come up correctly during boot
Status in linux package in Ubuntu:
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
