Except when the bisection points us to a patch exposing a bug that is present regardless (see http://lkml.org/lkml/2007/6/13/273 for example). Besides, if a patch is merged before -rc1 as a bugfix, there are several patches depending on it and only after -rc5 has been released we find out that it breaks someone's system, then reverting it is not a solution, IMO. > > Often we don't know which patch (or even which subsystem merge) is at > > fault. > > > > I think.

People should test _all_ of the -rc kernels and report problems. Otherwise, we may assume that there are no problems and go on.
