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.
