Yes, I set bootloader(arch/ppc/boot/ns16550.c)  and DINK (sb -k

38400) to 38400.

So where do I change the baud rate for kernel ?

Take a look in include/asm-ppc/serial.h at the define of
BASE_BAUD and it's use in
STD_SERIAL_PORT_DEFNS.

Isn't it for the clock divisor?  What happen if I want to return to 9600 baud?

How about changing  the line
"serial_driver.init_termios.c_cflag = B9600 | CS8 | CREAD | HUPCL | CLOCAL;" to
"serial_driver.init_termios.c_cflag = B38400 | CS8 | CREAD | HUPCL | CLOCAL;"
in rs_int() for the serial device and
"int baud = 9600;" to "int baud = 38400;" in serial_console_setup() for the console.

Both in drivers/char/serial.c

Yes, you're right.  Sorry, I was thinking of something else.
