mips exceptions problems

I am modifying the tr3904 mips bsp to be used on a Hurricane board that I purchased. It  has a QED r5231 processor.

I am trying to replace the interrupt vector that is first installed by PMON with my own,
but continually find that the PMON's is called regardless of what I do. I have checked the interrupt exception's  memory (0x80000180) and discovered mine is there. I have also tried to first flush the data cache and then invalidate the instruction cache but have no success; suspecting that might have been the problem.

The PMON vector continues to print "Interrupt Unknown".

Does anyone know what I am doing wrong?

Any help is greatly appreciated.
