The problem I'm seeing is this - the wdsc driver deadlocks itself when

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.

Is anyone else seeing this?

Works for me:
sd0 at scsibus0 target 1 lun 0: <IBM, DCAS-32160, S65A> disk fixed
sd0: 2063 MB, 8188 cyl, 3 head, 172 sec, 512 bytes/sect x 4226725 sectors sd0: sync (100.00ns offset 12), 8-bit (10.000MB/s) transfers, tagged queueing

I get this:
scsibus0: waiting 2 seconds for devices to settle...

'LCI' as in 'Last Command Ignored' according to the wd93c33 header.

And I have a ZIP drive with termination enabled on the external SCSI port. Removing it doesn't change a thing.

Note ID 0 is occupied by the host controller on SGI machines.

Yeah, I found that out when setting the 2nd drive's ID to 0 - ARCS would complain loudly.

have fun
