Actually, yes ;-) Well, I have a couple of new systems sitting on my desk, and between two systems (which for the moment get powered down / rebooted often) and multiple disks, I've been seeing a lot of such messages. Somehow I had got the impression that the messages recurred within a single run period, but I gather now that's not supposed to be the case. For some reason also I get multiple copies to a console logged in as root, like ... (da0:ahc0:0:0:0) tagged openings now 51 (da0:ahc0:0:0:0) tagged openings now 52 (da0:ahc0:0:0:0) tagged openings now 49 in bright text, followed by ...

Whatever context I was in gets scrolled right off the screen. It would be nice if these messages could be tamed in some way (like only the last in a count-down sequence issued), or made optional, or issued only when critical. -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
