Something else I noticed today: I've just got a new disk that supports NCQ and found the kern.cam.ada.ada_send_ordered sysctl that appears to enable/disable its use (?). But the shutdown handler that spins the disk down only gets initialized if ada_send_ordered is enabled. I was wondering what the reason for this is? -- Bruce Cran
