Hi,

I'm working on a Dual-PIII system with an SMP kernel 2.2.0 and RTL2D.

I've tried rt_task_make_periodic and it works fine.
So , I give you my exemple in order to try it on your system ( it's very
simple ,
but it is just to test the periodic task. ).

While making this exemple , I've done a bug at first ( which look like
your pb :) :
  I forgot that the periodic function MUST NOT END ( I didn't use perioc
function for a while). It have to be an unended loop ,
and rtl_sched will only unblock the rt_task_wait() of your function.
The pb I got , forgetting that at the beginning , was a freezed system !

Good Luck.
