Can you please enable CONFIG_DEBUG_LL and CONFIG_EARLY_PRINTK
in your .config? Then also append earlyprintk to the bootargs
above. Then you should see more info on what goes wrong.

I'm suspecting you should use ttyS0 as the console instead
of ttyS3? That's at least what I have on my zoom3 board
with the extra debug board.

You should use ttyO for the omap ports, but zoom debug board
has external 8250 ftdi ports, so those show up as ttyS and
not ttyO.
