I see this with MO drives when no medium is in them at boot time.

Wait... it has worked with NetBSD before... same version of kernel?
In this case, it looks to me like a hardware problem of some sort (read: 
either the drive or its power supply are partly broken).

remote possibility:  somebody has sent a spin down command to the
drive, and it needs to long to spin up (I think the scsi disk driver
(sd) sends a spin up command to all drives it finds).
