This probably means ig_serial.c or the user-level serial driver
in drivers/ is misconfigured.  The kernel bootup messages get
shown via the KDB console, which gets routed to the driver
in the OKL4 kernel.  Once you get to Linux user startup 
output gets routed through /dev/ttyS0, which is backed by 
ig_serial.
