Of course for those. I was thinking about those which just change one register or things like this that I cannot identify the expected effect. If you agree, I'll enumerate the ones I've already noticed so that you just have to say yes/no/unknown on them. Don't worry, I don't want to spend lots of hours on this, since as I said, I do not receive any feedback from SATA users on 2.4 (neither positive nor negative).
