Problems with fcc_enet driver for MPC8248 (2.6.12)

I'm working on an embedded board that is currently running kernel 2.4.28 without any problems. However, I am trying to upgrade from kernel 2.4.28 to kernel 2.6.12 and I'm unable to get the fcc_enet driver to work properly. The fcc ports are connected to ethernet phy devices. The receive and transmitted data out of the ethernet phy devices is all 0xff.

I tried using the fcc_enet driver from the 2.4.28 kernel on the 2.6.12 kernel but get the same results. This leads me to believe that the core initialization of the MPC8248 has changed on kernel 2.6.12.

Has anyone got the fcc ports to work properly on the 2.6.12 kernel ? If yes, how ? Did the MPC8248 core initialization change ?

Thanks,
