That's already interesting. Now what you need to do is to find
the kernel version that broken IrDA. You start with a 2.4.18 from
kernel.org (that should work, unless it's a Red-Hat thing) and work
your way toward 2.4.21 until it breaks.
Also... I strongly suspect it's an irq problem (irq 0 doesn't
exist). So, please check the output of "setserial /dev/ttySX" for the
serial port used.
