code looks pretty normal.  Check that t9 (aka register 25) is set up
on entry to the function.  I believe it is supposed to be set to the
function's entry point by the caller (something to do with PIC code).

I would stop at the function entry, dump the registers, step through
it (and the call to serial_setbrg) and watch the stack pointer.  Dump
the stack contents at different points and see where things go
haywire.
