I debugged this problem a little more and realized that the reset was happenning right after the execution of the first kernel instruction at 0x0000000c. The instruction at this location was "mfpvr r28". I traced this back to a snippet of code that was dealing with pipeline depth issues on the MPC8260. Once I commented this code out, more instructions were issued but the reboot happens elsewhere. I am not able to pin-point the location of the debug since my BDI fails to catch the reset when it happens. Can someone point me to the cause of this situation? Thanks in advance.
