I've already been informed about this by someone else. You probably have Western Digital Enterprise drive(s) on that SCSI bus or other similar drives. Disabling target initiated Sync/Wide negotiation makes the errors all but disappear. I'm working on getting one of these drives that do the target initiated Sync/Wide negotiation so I can get this taken care of for 5.1.20.
