Output from > "sensors": > > w83782d-i2c-0-2d > Adapter: SMBus AMD768 adapter at 80e0 As a datapoint, the same W83782D on AMD756 (also I2C) works correctly with 2.6.22: w83782d-i2c-0-2d Adapter: SMBus AMD756 adapter at 50e0 Jean Delvare recently worked on the ISA interface to these chips but it seems this would not be the cause if you are also using I2C. Our hardware appears rather identical... I've attached (an excerpt of) my /etc/sensors.conf -- I once dug through the datasheets for those compute lines for example so perhaps its still useful even if 2.6.21 working for you probably means you don't have a config problem.
