This changes existing behaviour. RTEMS is poor at cleanly handling the console
output on reset. Working with the powerpc/mvme2700 and EPICS is hard because the
output is lost on reset and assert and crash output is corrupted.

As an OS I think we should be heading other way and if you want just a reset you
provide it.
