I suggested to enable your new scheduler implementation as the default <br>
to check if it is in line with the standard schedulers. I would first <br>
get some high level data. Select a BSP with good test results on a <br>

the default, run the tests, record the data. Then get all tests which <br>
fail only with your scheduler. Do a high level analysis of all failing <br>
tests. Try to figure out a new scenario for the test smpstrongapa01.<br>
<br>
Do all the development with RTEMS_DEBUG enabled!<br>
<br>
Add _Assert() stuff to your scheduler. Check pre- and post-conditions of <br>
all operations. Check invariants.<br>
