LM Sensors Group: I compiled and installed the the latest lm_sensors, enabled i2c in my kernel an compiled it but it doesn't work. I have i2c 2.8.8 and sysfs and procfs support compiled in my kernel. The only thing i see wrong i when i boot intro linux (Mandrake 9.1) the first thing i see are i2c error messages. Here's the code: [szakats at nitro lm_sensors-2.8.8]$ sensors Can't access procfs/sysfs file Unable to find i2c bus information; For 2.6 kernels, make sure you have mounted sysfs and done 'modprobe i2c_sensor'! For older kernels, make sure you have done 'modprobe i2c-proc'!
