I now get the attached output.  Notice the "VFS: Mounted root (NFS
filesystem) readonly." message.

At some point, long ago, the generic kernel root mounting had
a subtle change for some reason.  The result is that all file
systems are now mounted read-only by default.  All you need
to do is add "rw" to the command line.  It should look like
this: root=/dev/nfs rw......Now, the more interesting part is
I thought I did that as part of the default command line in
arch/ppc/mbxboot/misc.c......where did it go?

I am working with the embedded-2.2.5.tgz archive.  The default option
for NFS is "root=/dev/nfs".  There is no rw option.  Anyway, I use the
boot prompt to specify my inet addresses rather than setup a bootp
server.  I use the following options
"root=/dev/nfs nfsaddrs=203.21.127.150:203.21.127.160
nfsroot=203.21.127.160:/sys/myroot rw debug".  The rw option works as
the VFS message no longer says readonly.  I can't see any difference
with debug option specified or not.

I still get the same results.  ie. /bin/sh gets invoked but I get no
prompt and I can't type anything.  I will try the nfsd in the foreground
as suggested by someone else.  tcpdump suggests that the nfs server is
doing arp requests for the 860 system but is getting no repsonse.  Maybe
the network driver has some problems (most likely with my port to SCC4)
?
