OK, that makes two with the same problem. I checked your config file
against mine and I can see no relevant differences, everything which
matters for net booting is the same. However, in my case the NIC driver
never comes in, neither does the serial driver (I tried using a serial
console). Also, I can boot from a floppy with lilo, which does not depend
at all on dhcp/bootp/rarp. Well, there is _something_ broken in there...

Any more net booters out there having the same problem? If you haven't
yet, have a crack at 2.2.18. Looks like it breaks NFS root, and that is
something that should be looked into...

I'm forwarding to linux-kernel as requested, but I did receive two copies
of your message, so I guess it circulated OK.
