Hi!! I have two asus p5a-b motherboard. The first one is Rev 1.03, the second one is Rev 1.04 In the bios i see the cpu and mobo temperature, it works fine. I using kernel 2.6 This mobo needs ALI15X3 hw bus, and Winbond W83781D sensor chip driver. With these drivers i see the sensors on sysfs. The only difference is with rev 1.04 the i dont see the mobo temperature value. It show constantly -48 celsius. (bios shows correctly) MB: -48.0?C (high = +80?C, hyst = +75?C) With 1.03 mobo the mb temp is showed correcty. The cpu temp, voltages and fan speed is showed correctly on the two mobos. I am using same bios on the two mobos. I tried with kernel 2.6.6 and 2.6.7. Is it a sensors bug or something wrong with the mobo? fako
