I don't think you should look at the CAM integration as a precendent for the current ATA situation. We had a switchover from the old SCSI layer to CAM instead of a transition because it would have been much more difficult to have both SCSI layers in the tree at the same time. In the case of the ATA code, both it and the wd driver have existed in the tree for quite a while, apparantly without problems. So I don't think there is a real parallel there. IMO, if the ATA driver supports all the chipsets that the wd driver does, then it's probably okay to throw the switch to get people testing the new driver. If it doesn't, though, I think we should wait on throwing the switch until it supports them all. Unlike the CAM case, there isn't a compelling reason to throw the switch before the new code supports every chipset.
