Not on anything that landed in my inbox I think, but that's not the point. For a regression report you need _2_ kernel versions, one with and one without the 'problem'. Providing one (or two) that have a problem doesn't qualify. In any case, I didn't see the original email, but I got the impression that it was complaining about 'new' behaviour from the bits I did see as quoted.
