The following reply was made to PR kern/10332; it has been noted by GNATS. From: Torbjorn Granlund <tege@matematik.su.se> To: "Kenneth D. Merry" <ken@plutotech.com> Cc: FreeBSD-gnats-submit@FreeBSD.ORG, gibbs@FreeBSD.ORG Subject: Re: kern/10332: System freezes during certain SCSI activity Date: Tue, 02 Mar 1999 01:40:24 +0100 Ken, Thanks for the reply! Yes, the timeout would sound like a cabling problem to me too. But the fact that I have run the system w/o any problems with the same LVD cabling for 1/2 year tells me the cabling is fine. I added the tape unit lately, and that on the SE bus. That started the problems, but I am unwilling to remove the tape unit. And yes, I have proper LVD cabling for the 4 disks (a messy cable with lots of twisted pairs...). The tape unit is connected with a plain old 50-pin cable. I have terminators in place (on the cable for the LVD bus and in the tape unit for the SE bus). If this is some sort of cable problem, why does it take hours to make it happen? And why cannot FreeBSD recover from the problem? I have had cable problems in the past (with plain Ultra devices), and then FreeBSD was always able to recover (within a minute).
