Subject: Is there any support for this card?
Sender: owner-freebsd-scsi@freebsd.org

A while ago I posted this on freebsd-questions and got no response.  I'm
wondering if this card is supported any longer, and if so, what further
steps I can take to try to get it working.

Thanks.

Subject: nca SCSI driver problems

I've got a Trantor SCSI controller -- which is supposed to be supported --
but I can't get it working on FreeBSD 2.2.5.  The card came with a ``NEC
SCSI interface'' booklet.  I see three chips on the board: the bios,
a motorola chip, and one marked:
	
	TRANTOR T101
	S9406AJ
	(c) NSC 1992

The only device I have attached is a NEC external CDROM.  It works from
dos, and it seemed to probe fine from FreeBSD.  However as soon as I try to mount
a cdrom, I get a kernel panic.  It appears that the panic is due to the
initialization code in the driver failing to undo something -- it leaves
the driver in a partially configured state -- so the panic isn't the crucial
problem.  Before I go further, here are the kernel config lines and the boot
probe messages:

  controller	nca0	at isa? port 0x360 bio irq 10 vector ncaintr
  device	cd0	at scbus0 target 1
  device	sd0
  device	st0

With a ``mount -t cd9660 /dev/cd0a /mnt'', I get:

  Nov 17 00:03:23 base586 /kernel: nca0/1/0 (cd0) timed out

and then a panic (page not present).  Next, I compiled the driver with
DEBUG enabled, and then got this on the boot:

The first message above is the first indication that things are
not working.  It causes nca_init() to exit -- I think -- prematurly
which eventually results in the later panic.  (BTW, I tried running
the driver in its non-interrupt mode, but the results are the same.)
I then went into the driver and hacked away... I increased timeouts,
ignored error returns in nca_init() and nca_select() just to see
if I could get any more info -- I figured that if it was just the
initial probe that wasn't quite right, maybe things would settle
down during normal operation.  Well, it now looks like the driver
just can't talk to this card successfully.  Running the driver in
interrupt mode, there are so many boot messages that dmesg can't
save them all.  Running the driver in poll mode, here are some log
messages from my brutally hacked driver while trying the mount:

I do see the ``busy'' indicator turn on on the cdrom drive, but
it seems as tho the driver just can't talk to the board correctly....

So where can I go from here?  Should I write a PR?  Does anyone
support this driver?

Should I dump the card and try to find an inexpensive NCR/symbios? controller --
if so, what are they called now?
