>From the output:  put_name is hit and produces the first three lines,
If it is hit a fourth time then rtems_task_wake_after is waking the tasks, the timer
is  working (time may still be off), and I would check if it was getting to the console

However, if it doesn't reach it a fourth time the context switch is probably not 
occurring correctly.
