Well, I have a (more) working system.  The se code calls the SCSI code
with SCSI_NOSLEEP.  In scsipi_done(), the wakeup() call is conditional on :

	if (!((xs->flags & (SCSI_NOSLEEP | SCSI_POLL)) == SCSI_NOSLEEP)) {

so the wakeup doesn't get called.  I removed the SCSI_NOSLEEP flag from
se_ifstart() and se_recv() and ifconfig now returns.  I must be still
missing something, because how does this work on other parts - if_se.c
and scsipi_base.c are MI?

Unfortunately, this doesn't make the interface work.  If I try and ping
the other machine, no packets appear on the wire.  se_ifstart() doesn't get
called either.  Closer but not close enough.

Aha!  I've just read the notes in ncr5380.doc.  I was wondering if there
was something different in the MI code that didn't display the problem
with the se code.

Yes, I'd noticed the profusion of zs drivers in the source tree (it was
mentioned in -current a while back too).

Thanks,
