It may be that you're getting a conflict in SCC usage. Make sure you
have CONFIG_SERIAL_ATM undefined. But if you really need it make sure
CONFIG_SERIAL_ATM_SCC is not used by anything else. You may also want
to disable CONFIG_PTP_SWITCHING if you don't need it. Finally you
probably want CONFIG_PHY_OTHER instead of CONFIG_PHY_SUNI_155 or
CONFIG_PHY_ATM_25. These latter options make assumptions about the
memory mapping of your phy.
Note: a long while ago we had problems with PTP switching causing hangs
but this was fixed by a ucode patch from motorola. If you really need
PTP switching you should get this.
