I'm doing that in my application and it works fine.

I have:

  switch ( scanpulse ) {
   case 63:
        rt_task_wakeup( &t_process_pulse );
        break;

   default:
  }

at the end of the ISR code.  The above code triggers the task every 64
interrupts.



In the init code I have:

 rt_task_init( &t_process_pulse, &process_pulse, 0, 1024, 1);

and

 the task is (simplified) :

  while (1) {

   /* do stuff */

   rt_task_suspend( &t_process_pulse);
  }





I can clearly see on a scope, diagnostic pulses being generated with each
interrupt and a separate one in the task.  The jitter between then is a
handful of microseconds.
