Do you mean it worked with the 21(decimal). If this is so, I think you are re-mapping the PIC wrongly which overlaps your interrupt and Exception handlers. This will definitely cause errors later on (if they havent so far). You should be mapping them after the Exceptions (i.e. from 0x20 onwards)

I changed it to 0x21 (hex) a long time ago.
