Hi I am trying to get ethernet working with the current fs_enet patchset from Scott Wood. I have added this along with the PPC_CPM_NEW_BINDING patches to Kumars current tree.
I ma having trouble with phy_connect/phy_attach similar to what was broken without the fs_enet patchset. It turns out that it is caused by fs_enet_mdio_bb_exit being registered with module_init(). I guess it should have been module_exit() instead... Also, fs_enet_mdio_bb_exit does not work, as shown in the log below. Not that I need it, but I guess it should be working when it is there. Here is a log showing both above described problems.
