[9fans] 53C896

[Christopher Nielsen]

It seems the fileserver kernel isn't all that happy with the
built-in SCSI controller on my MB (Symbios 53C896). I'm not
all that surprised from what I've seen in the archives, but
I decided to give it a go, anyway.

I've re-tooled the emelie kernel with extra debugging. The
output of which is below.

Any ideas on where to start with better support for this
controller on the fileserver? Jim, Nigel, do you have any
patches that would be useful? I'm more than happy to be a
guinea pig for patches and/or dive into the code.

There were actually a few problems, all of which have been
solved with help from Jim and Nigel.

1. I forgot to include the second scsi controller in
   plan9.ini
2. I had the controller numbers reversed (I was following
   what the scsi firmware boot messages said)
3. I updated the driver source to Nigel's most recent
   version

So far, eveything seems to be working as expected, though I
haven't really run the system through its paces just yet.

Thanks again to Jim and Nigel.

config w1.0.0

isn't that controller 1, device 0, lun 0?
but you've got the NCR at scsi#0 not scsi#1

panic: scsiio: device = w1.0.0

i think it might be saying `no such device (because no such controller)'.

plain w1 is device 1 (lun 0) on controller 0.
w1.2 would be device 1 lun 2
w3.1.2 would be controller 3 device 1 lun 2

i might be wrong;
it has been a little while since
i've had to write a device configuration.
(i get to do it next week when our jukebox arrives.)
