Hi Michael,

I am unable to reproduce this issue. I have written the following 
kernel code:

#include <native/timer.h>

int init(void)
{
	rt_timer_set_mode(0);
	xnprintf("mode aperiodic, ticks2ns: %Lu\n", rt_timer_ticks2ns(30000));
	rt_timer_set_mode(1000000);
	xnprintf("mode periodic, ticks2ns: %Lu\n", rt_timer_ticks2ns(30000));
			
	return 0;
}

module_init(init);
MODULE_LICENSE("GPL");

And I get:
[   17.366373] Xenomai: mode 0, ticks2ns: 30000                                    
[   17.370918] Xenomai: mode periodic, ticks2ns: 30000000000                       

Which is the expected behaviour.

Could you send us a test case allowing to reproduce the issue you 
encountered ?
