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.
