A still not working, but cross-compiled kernel

[Simone Piccardi <Simone.Piccardi@fi.infn.it>]

Hi,

Thanks to all your suggestion and help I finally get out from the kernel
cross-compilation; I obtained a zImage file that boot in the same manner
of the Gabriel Paubert images (i.e. still crash on the ethernet deriver,
but in the same way), so at least I can be confident that the
cross-compilation procedure is going right.

Next problem is to get the ethernet working: I tries to change the
ethernet setting as suggested; the output of the SROM command is this:

I tried to put on 1E location (that one marked above) the value 0 but
the results were the same of before the changes, the kernel crash:

I tried also to apply the Matt Porter patch for dec21143 to my kernel
tree, but it didn't work (probably because it's based on kernel 2.2.5
and I'm using a 2.2.6 patched kernel). 

Still I'm working on setting up the bootp server and to build the root
tree, but I don't think that this can cause the crash of the system.

Many thanks to everybody. 

Bye
