Also, The stack trace for the thread looks like this:
Tasks (entry function) -> rtems_task_wake_after ->_Thread_Dispatch_direct -> _Thread_Do_dispatch (where the _Context_switch function call lies), how can then the heir thread start executing from the _Thread_Handler? I do not see it in the trace at all.
