Are you crazy? :) Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I just got a Symbios SYM22801 (53C876-based) card handed to me last week, and I decided to put it in my machine to replace a less-capable Adaptec AVA-2904. I've run into an interesting problem. I'm not sure if it's cabling-related or not, but the cables do seem to make a difference. Here's how my setup works: ID 5 ID 6 +-----------------+ +-----------------+ | UMAX scanner |----narrow SCSI---| Archive DDS-1 | | (Astra 1220S) | | | +-----------------+---terminator +-----------------+ | | CS Electronics 68-pin VHDCI<->50-pin Amphenol cable -->| | +----------------------+ | (ext 68-pin) | | SYM22801 channel B | | | | (int 50-pin) | +----------------------+ | | ID 4 +----------------------+ | TEAC CD-R55S | | (terminated) | +----------------------+ Now, here's the interesting part. - When I have *only* the external cable connected, the channel works without errors. - When I have *only* the CD-R55 connected, it also works fine. - If I have the external stuff on channel A, and the internal stuff on channel B (or vice versa), that works. - However, when I have both connected to channel B, I get this mess: sym1:4: ERROR (0:48) (2-21-0) (f/35) @ (scriptb 2e8:11000020). sym1: script cmd = 88080000 sym1: regdump: da 10 80 35 47 0f 04 0a 01 02 00 21 80 01 09 00 00 52 dc 01 08 ff ff ff. (noperiph:sym1:0:-1:-1): SCSI BUS reset detected. over and over again, until I reboot the machine. I've not yet tried the old ncr driver on it. I've tried setting the channel switches to INT50 ON and HIGH TERM ON, but to no avail. I could put the CD-R on channel A for now, but when I get a SCSI disk to go there, I want to reserve channel A for it and other-high speed stuff, and channel B for the slow things. Any idea what's going on here? -lee -- +--------------------------------------------------------------------+ | Lee Cremeans -- Manassas, VA, USA (WakkyMouse on WTnet) | | lcremeans@erols.com | http://wakky.dyndns.org/~lee | To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
