Answering your questions in reverse order:

We routinely run test_libs=all on an ARM1136-based board.  It's under  
platforms/imx31.  However it sounds like you're using an ARM1176-based  
board.

I'm not sure whether there are any intricate differences between the  
two platform ports that is making the test libs fail on your board.  I  
don't think that is likely, though.

What THRD1200 does is to spawn a number of threads, each give them a  
4K stack, and make them run the worker() function.  The worker()  
function in turn writes data onto the stack and reads them back to  
make sure the values are sane.  The worker() threads are then killed  
at the end.

So this test case tests both thread creation and mapping.

My suggestions:

  - try recompiling with DEBUG_TRACE=5 to see if you see any  
additional error messages.
  - decreasing the value of N_THREADS.
  - checking whether the memory layout for the arm11-based board  
you're porting to is sane.
