Sorry, continuing this discussion doesn't make sense. You have the same hw, so just try enabling netconsole with 3.14 and use dhcpcd from userland (this does the final reset here which hangs. But don't suggest me (or insist on) a time consuming and totally useless bisect when I already know what makes the problem to appear (100% reliable here). I have better ways to waste my time.
