    The UTL_halt function gets called after an exception has occurred (among other places).  Early in the startup process (i.e. prior to main) is when the NMIE bit first gets enabled.  You may want to step through some of the code prior to main starting at c_int00.  If you ever see bit 1 of IFR set (i.e. IFR = 0x0002) then that means an exception/non-maskable interrupt has occurred.  In that case you want to look at EFR and IERR to see what caused it.
