You, on the > other hand, have seen similar errors like that before and can at least You seem to forget that I'm not reading LKML regularly but I do linux-ide (I know that the same is true for some other people) so I would have helped much earlier if I had noticed the *initial* mail instead of the most recent at the time... > have a hunch - and you did.

That is missing the point -- we are not the only knowledgeable ones here and we definitely want to encourage other people to attack the problems. [ Please read my mail again. I explicitly said "people" not "you" there. ] > But I'll start CCing linux-ide if that's your preference. Thanks but my preferences are not the point here. That is just the most efficient way for everybody: IDE/ATA problems should be handled at linux-ide mailing list. You can still cc: me but cc:ing linux-ide takes priority. Thanks. Bart
