Yes, now if you find the culprit option, it would be nice to report here
so that we can fix the I-pipe patch.
I do know it still. All i have are two configs. One which does not work

at 400us (i reckon this is nothing extra demanding from atom @1.6G)
the thread's loop looks like:
{
function1()
..2()
..3()
..4()
rt_task_wait_period()
