I see them also in the ASC/ASCQ table of SCSI-2 (and thus they are
certainly also in SCSI-3), but the reference in the text for those
messages is only for READ SUB-CHANNEL.  Nevermind.

Nope, the ILI case doesn't cause any message to be printed.
Obviously, cam_periph_error() eventually returns to saerror() with a
return code of 0, and without printing anything.

(Just to clarify: bootverbose was set, of course.)

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