Though we have no solution yet, you may want to read the thread: http://archives.andrew.net.au/lm-sensors/msg03681.html I would recommend to both of you to update to i2c and lm_sensors 2.8.0 (unless you are using a 2.5/2.6 kernel), since significant changes have been made to almost all drivers. Apart from that, I'm in no way an I2C/SMBus bus driver expert, so I'll keep quiet and let the other members of the list speak up. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
