So you are not getting interrupts. 

Does the port receive at all? Can you talk to redboot via this serial
port? Redboot will use any port when it starts up and then locks to a
port. So try minicom'ing to the second serial port and boot the
board. See if you can get redboot to respond. If it does you know that
polled IO at least works for that port. If it does not work its more
than just interrupts missing.
