I have currently no time to help you debugging this issue.

Each thread starts the execution in _Thread_Handler(). A context switch 
returns to _Thread_Do_dispatch() or jumps to _Thread_Handler(). The 
_Thread_Handler() completes the context switch, does some general calls 
to begin the thread execution and then calls the thread entry function.
