If you consider, for the moment, not pushing the patches in 3.4, = (because of stability concerns, or you judge these patches intrusives, = or whatever good reason), I won't do either, because I have no vision of = the potential problems with the patched kernel. I always try to stay on = pure vanilla kernels, longterm if possible, because stability is the = more important. My best bet is probably 3.8 kernels right now (even if they are not = longterm), or maybe simply going back to 3.2.
