Hello, Poul-Henning.
You wrote 7 =E0=EF=F0=E5=EB=FF 2013 =E3., 23:31:50:

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?
