25 *  _Internal_error_Occurred
26 *
27 *  This routine will invoke the fatal error handler supplied by the user
28 *  followed by the the default one provided by the executive.  The default
29 *  error handler assumes no hardware is present to help inform the user
30 *  of the problem.  Halt stores the error code in a known register,
31 *  disables interrupts, and halts the CPU.  If the CPU does not have a
32 *  halt instruction, it will loop to itself.
33 *
34 *  Input parameters:
35 *    the_source  - what subsystem the error originated in
36 *    is_internal - if the error was internally generated
37 *    the_error   - fatal error status code
38 *
39 *  Output parameters:
40 *    As much information as possible is stored in a CPU dependent fashion.
41 *    See the CPU dependent code for more information.
42 *
43 *  NOTE: The the_error is not necessarily a directive status code.
