GNU ld version 2.9 (with BFD 2.9)

after I added CFLAGS += -save-temps in /usr/src/linux-2.1.xx/arch/i386/kernel/Makefile
>make
gcc -D__KERNEL__ -I/usr/src/devel/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe -fno-strength-reduce -m486 -malign-loops=2 -malign-jumps=2

process.s: Assembler messages:

make[1]: *** [process.o] Error 1
make[1]: Leaving directory `/usr/src/devel/linux/arch/i386/kernel'

I found:
#APP
614: movw 24(%esp),0(%ecx)
movw %ax,2(%ecx)
rorl $16,%eax
movb %al,4(%ecx)
movb $130,5(%ecx)
movb $0,6(%ecx)
movb %ah,7(%ecx)
rorl $16,%eax

suggestions ?
a compiler or gas bug ?
I don't know much about Intel Assembler.
