What does this have to do with hibernation? If it's a hibernation-only issue, then there is something wrong. Also, if it is an issue for normal power-off as well, then I wonder why this isn't an issue on Windows. Does windows not spin down disks at all? IOW, I really don't think this is correct. I _do_ think that correct might be: - maybe we just do something odd and different, triggering some BIOS behavior that isn't there under Windows. So we should power down thigns differently so that the BIOS. - quite possibly: we just should not spin down disks at all, and just flush them and do the "park" command thing. If we're _really_ powering off, the disks will spin down on their own when power goes away. Maybe that's what Windows does? So I really don't want to pull this, because I want to get more of an explanation for why we need to do this at all. I also don't think this is even appropriate at this stage in -rc. Is it a regression? If so, that just strengthens the questions above - what did _we_ start doing wrong that this is needed at all? Let's just stop doing that, not add some idiotic black-list for somethign that _we_ do wrong.
