Very Computer

Hey all!

I just got an Adaptec 2840VL (local bus), and put it on my
486DX4/100 for tape backup.  Unfortunately, I keep getting
the error message "panic: ahcintr: AWAITING_MSG for an SCB
that does nothave a waiting message."  There was no space
in "nothave" in case you were wondering...

I am running off 2.1 GA, and tried using the aic7xxx files dated
Jan 11, 1996, but with the same result.  Also removed my NE2100
card (thinking DMA conflict), without change.  Now have NE2000
and EGA/CGA monitor card, ISA (16-bit) IDE/COM/LPT card, and
the Conner 850 IDE drive.  Unplugging the SCSI tape (4mm WangDAT)
did not change anything.  No other SCSI devices.  Tried changing
card settings (bios on/off, different ports, different IRQs).

Before I spend some serious time absorbing the driver code, would
anyone have any suggestions?  I may just chuck the card before
spending (wasting?) too much time on this :-(

Thanks to all, and especially the FreeBSD team.  This has to be
one of the finest software productions I've seen in 15 years as
user and programmer.

I am using a 2842 (a 2840 with a floppy port) without incident, without
tape drives (one HD only).  Are you sure everything's okay
with termination, etc?  Do you have the card in a bus-mastering enabled
socket?  You don't need the BIOS enabled if you aren't using the card
with a hard disk.  Are you sure you don't have any conflicts with the
I/O addresses?

I'm sure the termination is ok, and tried the card in all VLB slots,
especially the bus-master slot.  I tried a few of the many (16?) I/O
addresses, with no change.  All the addresses are pretty high, anyway
(over $1000).  After giving up on the 2.1 CDROM drivers, I tried the
latest aic7770 drivers, with slightly different error messages.

One fellow suggested that I try different wait states, etc. on the
motherboard, but nothing changed....

Argh!  Thanks anyway for the reply.
