Ok, that's weird, I don't see the same kind of clock chip on i2c as the previous model had... Can you check the exact dividers programmed on the CPU and redo the calculation based on the bus frequency ? There is a do-clock-spreading property attached to the U2 ASIC, I don't know if it may be related, I'll have a look. Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
