Yeah it's both defined.
The nanosleep sometimes (mostly) works.
Only if some interrupts during the sleep i got this non-awaking behavior
it seems strange.
Maybe broke my memory or stack anywhere. Could you tell me where the
scheduler of rtems is located to that i can define a breakpoint into him
and check why my thread is not waked up.
I searching the timer interrupt function that really does the thread
