 a bunch of strange characters.

Okay, then its likely a simple baud rate issue.

The kernel, the bootloader, and DINK all need to be set up for the same baud
rate.  It sounds like you have dink and the bootloader setup for one baud rate
and the kernel is probably still at 9600.  Could that be the case?

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.
