That would explain why I see an "irq but nobody cared" message when booting the original system. This isn't the problem I meant though. When adding interrupt-parent = <&pcawan>; interrupts = <7 IRQ_TYPE_LEVEL_LOW>; to the phy node I get an error saying that there is no irq domain associated with this device. > Do you have CZ11NIC13 or older board revision? CZ11NIC12 is indicated on my board. Best regards Uwe
