* at91rm9200/irq/irq.c: he bsp_interrupt_dispatch routine does not
determine the correct interrupt source number. According to the
datasheet, the reading of the interrupt vector register (AIC_IVR)
notifies the hardware that the OS is taken care of the interrupt.
Only after AIC_IVR have been read can the correct source number be
read from the interrupt status register (AIC_ISR).
