Whatever is the process that acknowledges the interrupt (its not
HAL_INTERRUPT_ACKNOWLEDGE )
stops working (intreq signal stays low)
small file transfers are ok but long ones have more chances for this
event to happen . Apps that use the timer tick by themselves (no irq
produced by networking) are ok
