If it's an extended addressing eeprom, you probably need to

Ben,
I'm a little confused right now and need to have a closer look.
The EEPRM is a M24C64 from ST with extended adressing modes. There might
be something going wrong during probe or initial adressing.
I'll post as soon as there are more useful results ...
thanks,
Andre

Wolfgang,
I have indeed a LM75 on this bus - but it's not adressed.
The same I2C bus works fine on linux-2.6.25 including LM75 and EEPROM.
The oszi shows complete transactions with valid data.
I think it is as software issue.
Thanks,
Andre
