The problem I'm seeing is this - the wdsc driver deadlocks itself
when probing devices right after probing the first one. I ran into
this when trying to put a 2nd disk into my Indy - ARCS reports both
without trouble but NetBSD hangs after probing the first one.
There's nothing wrong with the 2nd disk - if I disconnect the other
one and netboot the machine NetBSD probes it just fine. Also, if I
swap SCSI IDs so the new disk is probed first it's still hanging
after probing the first device, so it's neither of the disks.
I don't know that what I'm describing here is your problem, but it's a
good out-of-the-box example of the kind of things to look for.
I once bought an HP Netserver drive for use in a Sun workstation. This
crazy drive worked fine by itself, but refused to play well with anything
else. Addition of anything caused everything on the chain to fail device
probes. After an agonizing process of elimination, I discovered that this
crazy drive actually responded to EVERY SCSI ID, regardless of jumper
setting, cabling, etc. I finally pulled out the docs that came with the
drive and apparently, it was made to do this, and was intended for some
sort of single ended arrangement.
Good luck figuring out yours...
