monte/natsemi problem

Hi.

I'm having some trouble with "two kernel monte" or possibly with
the natsemi driver:
I have a system which boots up 2.4.22 kernel and has natsemi on board
(DP83815). Then I get another kernel + initrd from a server and
try to boot it using monte. Actually at this point the part that is
on the system and the one that I'm trying to boot is the same thing.
So far so good... I succeed in booting the new kernel using monte 0.3.0
and load the nastemi module, but after the "reboot", there is no
response from the network - I try pinging my server, but it simply
times out. Notice that it's the same kernel that I use when
booting and there everything works fine, but somehow either monte
or natsemi screws things up.

I tried using newer natsemi, but it doesn't help. I'm trying
now to get kexec to work on 2.4.22, but for no success this far
(I just started).

Thank you in advance
Yan
