I don't understand.  I'd expect the test to run once there were enough tasks.  It sounds like a real bug.

You say that the PREEMPT task is blocking on "puts( "PREEMPT - rtems_task_delete - deleting self" );" and never gets to the rtems_task_delete() that follows that line, and I guess you're saying all the other tasks are also blocking on their respective "puts()" calls, and that's why nothing happens when I increase the number of tasks.

I assume the default termios mode for the interrupt driven console is line buffered.  Why isn't the output eventually finishing?  Why doesn't increasing the number of tasks to 8 let things run through?
