orange pi 3.4.39 missing GPIO interrupts in (kernel space) irq_handler

Hi guys,
I have played lot more with rpi board & now i am moving to new Orange pi. i have installed 3.4.39 with Lbubutu (LXDE). i have wriiten GPIO interrupt driver on rpi for my 26bit-RF reader. I am able to receive properly all 26 bits in irqreturn_t irq_handler(kernel space) on rpi. But when i have run same module on Orangepi its receives only 13 to 15 interrupts

. Is this problem of interrupt jitter? Is i have to enable any CONFIG from sun8iw7p1smp_defconfig? Or is I have to add any patch like rt_kernel PREEMPT_RT?

thanks & regards,
Sandip.

ditto... i really need to be able to use the interrupts for input from a wireless key fob.. unfortunatly it only send out singnals as the buttons are pressed and the output is brief (250ms or so..) and I don't want to be polling every 1/4 of a second! I guess I will look into how to buid a hardware 'toggle' type of device that could be polled every second or two.. even if I get something like that to work it seems avery bad solution..
