SVN rev 214279 on 2010-10-24 16:31:57Z by brucec
Mostly revert r203420, and add similar functionality into ada(4) since the
existing code caused problems with some SCSI controllers.
A new sysctl kern.cam.ada.spindown_shutdown has been added that controls
whether or not to spin-down disks when shutting down.
Spinning down the disks unloads/parks the heads - this is
much better than removing power when the disk is still
spinning because otherwise an Emergency Unload occurs which may cause damage
to the actuator.
