without seeing the hw file, i can only guess. make sure you:
- use unique addresses (the @xxx part)
- are routing the output lines to different input lines
- interrupt driver actually handles more than one input :)

i've def connected multiple Blackfin UARTs using the same model and had their
interrupts routed independently ...
