Speaking of domain validation messages I have noticed
that either the sym53c8xx driver or scsi_transport_spi is
getting noisier in this area.
After "hot plugging" a U160 disk on a unpopulated bus
and then scanning the bus there was lots of redundant
noise on my console and log. The disk had autospin off
so a START STOP UNIT command was needed followed by a wait
for the disk to spin up. This is what I saw in my log after:

Surely one "FAST-80 WIDE SCSI 160.0 MB/s DT (12.5 ns, offset 62)"
message is sufficient?
The READ CAPACITY/fetching the caching mode page sequence
seems to be occurring twice. I also see this with scsi_debug
so it isn't a spi or lldd problem.
