I got this message while compiling kernel 2.3.21 with binutils 2.9.5.0.12

---
gcc -D__KERNEL__ -I/usr/src/linux/include -E -traditional -DSVGA_MODE=NORMAL_VGA  bootsect.S -o bootsect.s
as -o bootsect.o bootsect.s
bootsect.s: Assembler messages:
bootsect.s:1023: Error: `%al' not allowed with `outw'

And the infamous code is:


kill_motor:
        pushw   %dx
        movw    $0x3f2, %dx
        xorb    %al, %al
        outw    %al, %dx		<< 1023
        popw    %dx
        ret
