Are you able to get the registers in GDB properly? The e500 introduces a different GDB register protocol than standard PPC. This either requires the latest GDB and possibly BDI firmware. I forget how BDI handles the different protocol layouts. I'm pretty sure they added support for "full e500 GDB" recently. You also, have to build u-boot and your kernel to handle the quicky debug support on 85xx. - kumar
