I've got:

uriah # cvs stat /sys/cam/scsi/scsi_all.c
===================================================================
File: scsi_all.c        Status: Up-to-date

   Working revision:    1.24    Result of merge
   Repository revision: 1.24    /home/ncvs/src/sys/cam/scsi/scsi_all.c,v
   Sticky Tag:          (none)
   Sticky Date:         (none)
   Sticky Options:      (none)

....and still have the problem that the "camcontrol start" doesn't
work.  It returns immediately to the caller, claiming a "unit started
successfully", while the drive hasn't started at all.

Issuing a "camcontrol command daX -c '1b 0 0 0 1 0'" works.

I didn't try whether the kernel-implied startup on disk access would
work, though, since it would IMHO risk a hanging kernel and controller
timeout.

Never trust an operating system you don't have sources for. ;-)
