Hi, It seems you did what I did not wanted. You need to have compiled lm85 module, when you will configure the kernel you can turn on also debugging in I2C submenu. Please run following commmands: 0) reboot 1) modprobe i2c-i801 2) modprobe lm85 force=0,0x2e 3) sensors Does it produce anything? Output, or in system log? >>1) reboot the computer > > > 1a) `modprobe i2c-dev` true I forgot :) > > > > Attached. I should note that the diff of before and after does show > several changed lines...
