Well, scsi is happier now.  The messages above are expected, and
test 1 passing means the scsi chip can access memeory ok.

Those messages might be caused by an unterminated scsi bus, or by
a problem with interrupts.

The network problem still looks like interrupts from the 82596 are
disabled somehwere and not getting to the processor.

Still seems likely to me that the kernel is not enabling some interrupts
properly for the 710 bushmaster machines.

Anyone on the list got a similar machine working?  The h/w database
lists quite a few people as owning one of these boxes.

My 715 now works as far as scsi and network are concerned, but (a) I
have to disable nscd, (b) tar hangs, and (c) I have disabled parallel
port support.  nscd and tar both seem to go in to a loop calling
sched_yield() from libc.
