FEC3 of MPC8309 can't work

[zheyin]

The configuration and the circuit of FEC3 and FEC2 exactly the same, FEC2 is working properly, but FEC3 cannot trigger the interrupt service routine(ucc_geth_irq_handler).

Attached is the source file of device tree and network device driver.

Linux version 2.6.33.7.2(gcc version 4.1.2)

Need help!Thanks a lot!God bless you!

OK.I got it just on Thanksforgivingday!

			rx-clock-name = "clk11";
			tx-clock-name = "clk12";

That's all right.Thanks God!

		enet2: ethernet@2200 {
			device_type = "network";
			compatible = "ucc_geth";
			cell-index = <3>;
			reg = <0x2200 0x200>;
			interrupts = <34>;
			interrupt-parent = <&qeic>;
			local-mac-address = [ 00 00 00 00 00 00 ];
			rx-clock-name = "none";
			tx-clock-name = "none";
			phy-handle = <&phy2>;
			phy-connection-type = "mii";
		};

?interrupts = <34>;

Interrupt ID Number is reserved!

But mpc8309twr-indctrl.dts used interrupt 34.Why?

Shoud I have another one?Which one?
