I've seen the same behavior with my Dell XPS 15 9550 that Rowan is describing with their Mac.

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).
