Well, tcpdump on the server doesn't tell much: the
"Requesting Ethernet address for 0.0.0.0" leads to:

(jazz is the server, toccata the client).
Then it uses NFS to load the kernel, and then, just before the panic:

looks like tocatta doesn't get its rarp replies or ignore them ...
I tried changing the network config, hooking the sparc on a hub instead of the
switch. I can confirm that these messages really go to the sparc (at last they
are seen by other machines of the hub).
