Also, the logs are incomplete; it looks like a bunch of stuff is missing from the start of the suspend.

Oddly, this log is much more complete than the others. Did you collect it the same way? This is very puzzling. Let's try one more combination. Can you collect a log showing 3.14 with commit 0aa2832dd0d9d8 reverted and the mouse & keyboard both plugged into the rear ports? Offhand, I'd say there's something wrong with the USB controller hardware on the motherboard. With incomplete information, though, it's hard to tell for certain.
