--- Comment #19 from Alex Deucher agd5f@yahoo.com 2010-08-07 10:23:09 PDT --- Please take the bisection to the end. if a commit is broken, mark it bad (git bisect bad) if it's working, mark it good (git bisect good), if you can't compile it or it won't boot, skip it (git bisect skip). at the end it should identify the exact commit which caused the problem.
