X-Mailer: Mozilla 4.76 [en] (X11; U; Linux 2.2.12 i386) X-Accept-Language: en MIME-Version: 1.0 To: stable@freebsd.org Subject: Reproducible kernel panic during boot; probably SCSI-related Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG We've had a reproducible problem today with 4.2-STABLE from between 2001/02/13 1500 PST to 2001/02/14 1500 PST, where the kernel would print the message "Waiting 2 seconds for SCSI devices to settle" and then panic (details below). This would happen every time. I rebuilt the kernel several times to make sure there were no stale dependencies but every time it panicked the same way. Eventually I cvsup'd /sys sources from 2001/02/10 and the problem went away. I presume the problem is still in -stable. I wasn't able to get a dump because *dumpdev = 0xffffffff. (Does anyone know how to get dumpdev set properly this early in the boot process? In -current one could use "show /disk/da0s1b" but we don't have that in -stable.) This is running on an L440GX mobo with one extra 2940 controller, for a total of three. Any ideas?
