Now as we are improving our lab we decided to try giving FreeBSD a real server machine. The machine we are planning on hosting FreeBSD 3.2 on is a Server style PC. Intel S450NX MP motherboard (as far as I can tell). It has a Symbios 53c810 & a Symbios 53C896 (the 53c896 appears to be dual 53c896's) built onto the motherboard. It also has an Adaptec 2940 PCI card. It has 2 500 Mhz Pentium III - Xeon processors with one GIG of RAM. I've tried several configurations, but when I leave the Symbios controllers on I get a Panic during the boot from CD right after the 15 second wait for SCSI to settle. The panic line looks like: Assertion "target==ccb->ccb.h.target_id" failed:file "../../pci/ncr.c,line 5097". I currently have the CD connected to the Adaptec controller and the SCSI disks connected to the Symbios controller. I was unable to get it to attempt to boot having all SCSI devices connected to the Adaptec controller with the Symbios disabled. This box is supported by NCR with LINUX installed. I'll contact someone at the factory to determine what that configuration is. I'll be playing with this over time. That's why I listed this as a medium priority. Any suggestions as to Symbios configurations would be appreciated. >How-To-Repeat: Attempt to boot (install the os) from the CD. >Fix: >Release-Note: >Audit-Trail: From: Stefan Esser To: Russell.Ingram@sandiegoca.ncr.com Cc: freebsd-gnats-submit@FreeBSD.ORG, Stefan Esser Subject: Re: kern/12632: Panic (trap 18) with Symbios SCSI controller "../../pci/ncr.c" line 5097 Date: Fri, 16 Jul 1999 19:53:00 +0200 --45Z9DzgjV8m4Oswq Content-Type: text/plain; charset=us-ascii On 1999-07-13 14:48 -0700, Russell.Ingram@sandiegoca.ncr.com wrote: > The machine we are planning on hosting FreeBSD 3.2 on is a Server style PC.

[ Please limit your lines to 80 characters ... ] Sorry, the 53c895/896 is not yet "supported" under -stable. I added code that works together with changes to some register in the U2W chips to the -current tree, a few months back, but when I was just about to merge them into the -stable branch, there was a single report of instability of a system with that driver, and I decided to wait for further feedback. Please let me know, if you find anything wrong with the patch, since I really want to have it in -stable. It worked without any problem for months on my (-current) test system with a Symbios Sym8951 card ...
