Thank You Dear Allon, I did not understan what is mean by return from ISR?
Your ISR is a function, invoked by the kernel. What value does it return?If you return anything other than IRQ_HANDLED, you might get a spurious interrupt message. If you fail to specify a return value, you might get weird results, maybe what you are seeing.
