Well, that's good to hear, at least I can provide a bit of entertainment ;-)

No, in that cases it looked like this:
-----------------------snip------------------------
0 > boot net 
LOAD: Waiting 60 seconds for Spanning Tree
BOOTP R = 1 BOOTP S = 1  
FILE: generic_com0.fs
Load Addr=0x600000 Max Size=0x10000000 
Packet Count = 100...FINAL Packet Count = 5181   Final File Size = 2652339 bytes.


-----------------------snip------------------------

The firmware printed a last newline and the box died on the spot,
like the firmware has a wrap-around on load or something like that.

Well, the first kernel with the option enabled died on boot-up,
is there something to watch out for? It was not selected in the GENERIC
kernel for prep anyway, so I think that's more work for later...

CU,
