(at least on my P2B-LS) Well, I don't know if *your* problems will go away (I'm not 100% sure that your problem is the same as my problem). However, my problem went away went I moved the cable to the plain "Ultra" (20MHz) connector rather than the "Ultra2" (40MHz) connector. Peak performance is lower (at least with multiple disks on the bus). Sorry, I thought that I had mentioned this someplace. Maybe I should submit a follow-up to the PR to mention this work-around. andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
