Jep - that seems to be the problem somewhere in 2.1 the arp state machine
seems to have moved and/or replaced. There seems to be an expiry problem.

Ok - got it - Works on the 5000/150 with console=ttyS2.
Currently i think the declance doesnt work for me - I have compiled
the kernel with Kernel Level Autoconfig/BootP and root-nfs but
i only get debugging messages from the declance driver although
i get the correct mac address shown ...

I was aware of that. I am working with the /150 as the booting is MUCH
faster as the BootProm of the /240 is a bit buggy and shows a debugging
line for every tftp packet which is a lot on a 1.3MB kernel and 9600 8N1 :)

Ok - where do i get a working declance ? 

I think i have to look into CVS to look into the vger CVS trees ...
