Last time I mentioned this, des@des.no also said then it was a well known ATA bug, for which I should look in the archives. However, as I said, it's hard to pinpoint from searching the -current archives, quite which bug he is talking about. Does anyone have a link to a post which goes into greater detail about this problem? I'd like to post a PR regarding this, but would like to read these previous posts to get a little more info.
