UCC interactions

[Gary Thomas]

I'm running 2.6.33.3 on MPC8358.  I have UCC1+UCC2 working fine
for ethernet, but when I add UCC3 as a UART, the network devices
quit working.

Here are my device tree entries:
          /* ETH0 (UCC1, MDIO 0x02, RMII) */
          enet_eth0: ethernet at 2000 {
             device_type = "network";
             compatible = "ucc_geth";
             cell-index = <1>;
             reg = <0x2000 0x200>;
             interrupts = <32>;
             interrupt-parent = <&qeic>;
             local-mac-address = [ 00 00 00 00 00 00 ];
             rx-clock-name = "none";
             tx-clock-name = "clk16";
             phy-handle = <&phy_eth0>;
             phy-connection-type = "rmii";
             pio-handle = <&pio_ucc1>;
             linux,network-index = <0>;
          };

          /* ETH1 (UCC2, MDIO 0x01, GMII) */
          enet_eth1: ethernet at 3000 {
             device_type = "network";
             compatible = "ucc_geth";
             cell-index = <2>;
             reg = <0x3000 0x200>;
             interrupts = <33>;
             interrupt-parent = <&qeic>;
             local-mac-address = [ 00 00 00 00 00 00 ];
             rx-clock-name = "clk4";
             tx-clock-name = "none";
             fixed-link = <1 1 1000 0 0>;
             phy-connection-type = "gmii";
             pio-handle = <&pio_ucc2>;
             linux,network-index = <1>;
          };

          /* ttyQE0 (UCC3) */
          serial_qe0: serial at 4000 {
             device_type = "serial";
             compatible = "ucc_uart";
             cell-index = <3>;
             reg = <0x4000 0x200>;
             interrupts = <34>;
             interrupt-parent = <&qeic>;
             port-number = <0>;
             rx-clock-name = "brg1";
             tx-clock-name = "brg1";
          };

Are there known interactions between these two drivers/ports?
Maybe there's something obviously wrong with my device tree?

Thanks for any ideas/pointers
