error rtai_serial

[dilodovico at jumpy.it]

Hi,
I can load rtai_serial.o  module, I have this error: 

insmod rtai_serial.o 
rtai_serial.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg

dmesg message:
TTY_INDX: 0, PORT: 3f8, IRQ 4.
TTY_INDX: 1, PORT: 2f8, IRQ 3.
# OF PORTS: 2, BUFFER SIZE: 512.
EITHER IRQ NOT AVAILABLE OR NO MEMORY AVAILABLE FOR READ/WRITE BUFFERS (TTY
INDEX: 0).

could you help me please?
thanks
