> Could you give me more information on how to "kill transaction after a > while"? I tried, but failed, maybe the codes I tried is not correct. Well thats hard without a datasheet. Maybe Patrick can do sometning like this I guess it is like two more lines of code. I'm not an expert of this subject. Maybe you can take a look to your windows driver sources if there is some problem recovery after a transaction and not just before as it is in ours. LHHsu: Please can you try to ask for that SMM mode question? If something is using the SMBUS controller we should know it. Thanks Regards Rudolf
