Hi, I have an Asus A7N8X-X mainboard with the asb100 (bach) and the w83l785ts chip. Latter one reads the internal CPU-temp-diode. When all needed modules are loaded it works really well including fancontrol. But the w83l785ts doesn't always work. When the module is inserted trough the lm_sensors start-script it is listed when doing lsmod but there is no /sys/bus/i2c/devices/1-002e/ directory. After I rmmod and modprobe the module (sometimes several times) everything works. When using Windows I realized that Speed Fan also sometimes failes to detect the w83l785ts-chip. Is this a known problem and do you know a workaround? There are no error-messages from modprobe, dmesg or anybody else. Here is my configuration System: Fedora Core 2 uname -r : 2.6.6-1.435.2.3 sensors --version : 2.8.6 cat /etc/sysconfig/lm_sensors: ----- MODULE_0=i2c-nforce2 MODULE_1=eeprom MODULE_2=asb100 MODULE_3=w83l785ts ----- cat /etc/fancontrol : ----- INTERVAL=10 FCTEMPS= 1-002d/fan1_pwm=1-002e/temp1_input FCFANS= 1-002d/fan1_pwm=1-002d/fan1_input MINTEMP= 1-002d/fan1_pwm=25 MAXTEMP= 1-002d/fan1_pwm=60 MINSTART= 1-002d/fan1_pwm=130 MINSTOP= 1-002d/fan1_pwm=90 ----- I hope this is all information you need Thanks for your help in advance and thank you for lm_sensors! Johannes H?bner BTW: I had to change pwmconfig a bit for it to detect the fanX_pwm lines of the asb100. In it s current state it only finds pwmX . I can send it to you if you don't know what I mean.
