Thank you for all your support. the `modprobe w83781d init=0` works and the system no longer locks. However, if I call: modprobe i2c-dev modprobe i2c-amd756 modprobe w83781d init=0 from /etc/rc.d/rc.local (RH7.2) while booting up, sound (SB Live Value) won't play. Not too important as if I leave them out and modprobe them after I boot sound is ok and it seems they still work so I only mentioning just for the cause. Now, it seems that the readings are completely wrong/out of the blue. Here's a typical: [root at zeus spxak]# sensors w83627hf-i2c-0-2c Adapter: SMBus AMD7X6 adapter at 80e0 Algorithm: Non-I2C SMBus adapter VCore 1: +1.87 V (min = +1.93 V, max = +2.14 V) ALARM VCore 2: +1.84 V (min = +1.93 V, max = +2.14 V) ALARM +3.3V: +3.29 V (min = +3.13 V, max = +3.45 V) +5V: +4.70 V (min = +4.72 V, max = +5.24 V) ALARM +12V: +9.84 V (min = +10.79 V, max = +13.19 V) -12V: -13.11 V (min = -10.90 V, max = -13.21 V) -5V: -0.24 V (min = -4.76 V, max = -5.26 V) V5SB: +5.51 V (min = +4.72 V, max = +5.24 V) VBat: +0.00 V (min = +2.40 V, max = +3.60 V) fan1: 3375 RPM (min = 33750 RPM, div = 8) fan2: 3125 RPM (min = 84375 RPM, div = 8) fan3: 0 RPM (min = 4963 RPM, div = 8) temp1: +78.0?C (limit = +81?C, hysteresis = +66?C) sensor = thermistor temp2: +4.5?C (limit = +80?C, hysteresis = +75?C) sensor = thermistor temp3: +8.0?C (limit = +80?C, hysteresis = +75?C) sensor = thermistor vid: +2.05 V alarms: Chassis intrusion detection beep_enable: Sound alarm enabled They system should report ~55C for the CPU's. I hope that even if my issue is not resolved, you can use the feedback. Thank you again A. Kambas.
