Yeah, google is your friend (at times). That would trigger a SCSI bus

It's odd that it's not seen at all except if plugged in at boot. Sounds
like a bug, although I don't know if it'd be in the SCSI driver, hotplug
code or kernel itself. I'd sure bugzilla it.
well, never opened a bugzilla in my (long) life.
May be this will be the first time.
