-----------------------------+-----------------------------
 The current rtems_panic() implementation is quite heavy weight. It depends
 on _exit() which calls the global destructors. It uses fprintf(stderr,
 ...) for output which depends on an initialized console device and the
 complex fprintf().

 Introduce a new fatal source RTEMS_FATAL_SOURCE_PANIC for rtems_panic()
 and output via printk().

 Document this function in Fatal Manager chapter.

 Replace all BSP_panic() with rtems_panic().
