The following reply was made to PR i386/20790; it has been noted by GNATS. From: Matthew Jacob <mjacob@feral.com> To: jimd@dutton3.it.siu.edu Cc: FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: i386/20790: Upgrade to V4.1 "kills" SCSI tape (rst0->rsa0) Date: Tue, 22 Aug 2000 16:19:59 -0700 (PDT) Do you actually have a tape loaded in the drive when you issue the 'mt stat' command? If so, it may be the code that tries to sense what media is there- this can break for some drives. Try building a CAMDEBUG kernel, reboot, do camcontrol debug -Ic 0:4:0 and then do the 'mt' test with a tape inserted and send me the results, thank you. > > >Number: 20790 > >Category: i386 > >Synopsis: SCSI tape drive no longer works > >Confidential: no > >Severity: serious > >Priority: high > >Responsible: freebsd-bugs > >State: open > >Quarter: > >Keywords: > >Date-Required: > >Class: sw-bug > >Submitter-Id: current-users > >Arrival-Date: Tue Aug 22 16:10:00 PDT 2000 > >Closed-Date: > >Last-Modified: > >Originator: Jim Dutton > >Release: FreeBSD 4.1-RELEASE i386 > >Organization: > Southern Illinois University > >Environment: > > FreeBSD 4.1-RELEASE #2: Tue Aug 22 00:52:51 CDT 2000 > jimd@dutton3.it.siu.edu:/usr/src/sys/compile/XSYSDELL41 > Calibrating clock(s) ...
