I'm at work right now, but hopefully I can supply the logs later.
How would I go about bisecting? It sounds like a nightmare, running through all check-ins between 3.12 and 3.13. Is there a guide, or some tips on what changes to check? Do I start in the middle to see if the problem is there?
Google for "git bisect howto". Git makes it really easy.
