Another board (Maybe later revision) is not showing this. We have tried a bios update and several FreeBSD Versions including some 4.0-current - but the problem still exists. I remember that boot -v showed something that I wanted to send to the FreeBSD-SCSI list - but I didn't yet because I don't have it logged. It stopped after probing some but not all drives before it would print the non -v informations. I expect this problem has something to do with the aic revision on that boards. I'll try to get the boot -v informations and the revision next week. > Steinar Haug, Nethelp consulting, sthaug@nethelp.no > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hackers" in the body of the message -- B.Walter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
