Hi Chunhao, > If you have more suggestion about this problem, please tell us, I'd like > to try it here. I don't, sorry. The information provided by Asus (write an arbitrary value to an arbitrary port) isn't sufficient for us to understand what happens. We would need detailed information on what chip we attept to control at this port and how that chip works, and also details on how the SMBus is wired. Without that information, I just cannot tell why the SMBus works first and then suddenly fails. > Btw, Is there any guys who are going to backport the i2c-ali1563.c from > linux-2.6 to linux-2.4?

I really don't know much about SMBus master drivers, so I can't help myself, sorry. -- Jean Delvare
