In RTEMS you have priority based schedulers. If there is a higher 
priority ready thread then a lower priority thread will not run.

You can use the RTEMS shell to figure out the status of a running 
system, e.g. use cpuuse and task commands. Make sure that the shell task 
has a high enough priority.
