I would agree with this.

A simple test is to find the bit of code that unmasks the interrupts for the 
FEC and comment it out. If the board does not crash it would seem the handler 
is the cause. It will not work but that is next.

Is it possible to get a BDM gdb debugger working on your board ?

If you could it would make things simpler to debug.
