cassini memory address trap.... same as on the b100s in the B1600
chassis I think -- I bet if you compile a kernel without device cas
it'll get past that bit -- problem then is no network...

Marius- I'll have a look at setting up a netboot server and look at
getting terminal and blade access for you this weekend if your still
interested.  I hope to help in anyway possible but me head exploded
after trying to debug the panic :)

That is if they are related...  IIRC you said something to do with the
way the BAR was getting assigned.
