Hi ,

I am working on ixp2800 and trying to bring it up using SNAPGEAR.

I have SNAPGEAR 3.2.0 and arm-linux-tools-20031127.tar.gz as my tool
chain.

I got a zImage using default setting for ixp2800, and linux 2.4.x
kernel.

I am able to launch it and insert modules using insmod. But when I try
executing it using the ./sa executable it reports the following errors.

=================================================================

Also the following errors are reported at the end.
=================================================================
 Backtrace: frame pointer underflow
Unable to handle kernel paging request at virtual address ffffffff
=================================================================


I desperately need guidance to continue.

Thanks in advance,
