(Just in case... I'm not native english some part are more understandable if you read-it as it sound!) SOLVED! (Or at least isolated...) That's what is happening... The new cables (U2W: The one with a terminator and with all the wire independently connecter to the connector (but still in serial fashion) ) are kinda having quite a ride on EMI... Yeap, your PC emit like a small Radio station! So you have to make sure where you route the cable throughout the casing. Like, Justin said: that the Adaptec Guys thinks it hardware... Some timing or access sequence were surely changed between 0520 and 0712 and made that problem appear more frequently. So a good SCSI hygiene and good posture (don't route the cable around the power, but near the casing following a single direction, not to pinch or apply stress to the cable or wire...) might generally solve the problem. (This can explain why some got 0x17d and others 0x17e... I was re-arranging it tonight when I start getting 0x2!) So, I'm mailing from a functional 0712 installation with a 3.0-current kernel (but I still have the patch Justin send us... Will see without it tomorrow, OK!) Have fun with your 3.0-19980716-CAM system. (I will for sure!) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
