PHK> So does the interrupt actually arrive ?

vmstat -i
interrupt                          total       rate
irq3: uart0 uart2                      1          0

It  doesn't  look  so.  And  uart1  and  uart3  doesn't have interrupt
according to `vmstat -i' (but share irq4 according to boot messages).

PHK> If not: Interrupt routing issue ?
 How could I debug this?
