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.

I examined the bus driver of i2c-i801.c, in the function
i801_transaction()
I do not find any codes which is similar to the following i2c-ali1563
codes:
	if (!(data & HST_STS_DONE))
		/* Issue 'kill' to host controller */
		outb_p(HST_CNTL2_KILL,SMB_HST_CNTL2);
	else
		/* Issue timeout to reset all devices on bus */
		outb_p(HST_CNTL1_TIMEOUT,SMB_HST_CNTL1);

So I will comment out the above six lines from i2c-ali1563.c temporarily
before we find a better method. So that my w83792d driver on work on
this motherboard SU-2S.

Thanks
Best Regards

Chunhao
