 are known SMP open issues so I assume if the tasking were stressed more there
 would be additional failures.  See the open issues below under SMP.

+An smp configuration was added.  This is not quite the same as the configuration that I used for testing.  I enabled DEBUG output, ran with only 2 CPUS, and disabled the RAMLOG:

+
+I would also disable debug output from CPU0 so that I could better see the debug output from CPU1:

+  ---
+    This is a configuration of testing the SMP configuration.  It is
+    essentially equivalent to the SMP configuration except has SMP enabled.
+
+    NOTES:
+
+    1. See the notest for the nsh configuration.  Since this configuration
+       is essentially the same all of those comments apply.
+
+    2. SMP is not fully functional.  See the STATUS and SMP sections above
+       for detailed SMP-related issues.
