so both parport and serial is on the same IRQ: #7, but the parport one
does not support shared interrupt lines (IRQF_SHARED). You can probably
change the mapping in the BIOS (change the serial one to say IRQ#3 or
IRQ#4). I suspect you dont have any real parallel port hardware
attached? (and probably no serial port hardware either?) So you can
safely ignore this.
