Unfortunately the RTEMS test suite output is not that useful currently.  A test 
program should only print out "END OF TEST" if it was successful.  Most tests 
do this.  Some tests (e.g. the smptests/smp06) have bugs and produce false 
positives.  An open project is to convert the RTEMS test suite to use a unit 
test framework with better human and machine readable output.
