In addition to the the stack initialization you would want to check
the  Interrupt vector routine addresses  also.if it is stored with the
correct address of the UART interrupt routine.One thing which you
could try is to ,install  a dummy function implemented for all the
unused interrupt vectors .and have a UART report back function in that
routine.So any false interrupt goes to the dummy vector and prints a
report string.I once had a problem that UART interrupt was recognised
as interrupt ID 0 where as the IRQ ID generated should be IRQ ID 2.If
need help just tell.
