lm-sensors

whenver I try to run sensros, it spits out complaints that it cant access procfs/sysfs files. The lm_sensors web page FAQ says that this is because either sysfs is not mounted or i2c-sensors module is not loaded. Well, sysfs is mounted (/sys is populated) so it must be that i2c-sensors is not loaded. The only problem is that I can not find anywhere in the kernel config to create a module called i2c-sensors (I have gentoo-sources-2.6.16-r

so what am I supposed to do? Others have posted about his or with similar complaints, but I have not found any solutions out there. Is there a solution?

You'll find the i2c devices in menuconfig under "Device Drivers" / "I2C support" / "I2C Hardware Bus support" and some more under "Miscellaneous I2C Chip support".

yes, I HVE those, but none are i2c-sensors, in fact I have EVERYTHING under i2c and hardware sensors built in as modules

Ok, then run "sensors-detect" and load the hardware-specific modules it suggests. There is no "i2c-sensors" module but those bus support modules.

I have the following modules loaded, for example:

no, no, no you guys do not understand, perhaps I am not being clear. I HAVE run sensors-detect, I HAVE the appropriate interface modules loaded, I HAVE followed set-up instructions, I HAVE included every possible module in the kernel, the FAQ on http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html specifically says that i2c_sensor is needed (4.20) but this module does not exist in the kernel. THAT is my problem, in order for it to work it says it needs a non-existant module to be loaded.

Ok, I'm sorry. My lm_sensors package works perfectly fine without loading a module called "i2c_sensor" that doesn't even exist in recent 2.6 kernels (I've checked your kernel version, too. :) ) and that isn't part of the lm_sensors package itself.

I've never made the acquaintance of that evasive module and I think I never will (and thus can't help you) but I wish you the best of luck hunting down that invisible beast. :)

I've also problems with starting lm_sensors and I don't know why :?:

Take a look at /etc/sensors.conf, edit it as needed and try again.

If it doesn't work, try running

I have done this, if you are talking to me that is, and the smae problem results. Unfortunatly, linuxtuxhellsinki has somewhat hijacked my thread with an unrealted issue with lm_sensors.

I have i2c-core built-in, in fact I cannot modularize it as it is required for another thing I have built-in (I believe it has to do with i2c access for radeon cards). Yes, I just checked, I have DDC/I2C Support for Radeon Cards builtin and thus both i2c-core and support for i2c bit-banging algorithms are builtin and not modularizable (f that's a word).

Ok, that's fine. Now please modprobe a bus support module of your choice, run "sensors -s" and post the output.

Please post the following information:

mount

ls -l /sys/bus/i2c

uname -a

ls -l /usr/src/linux

grep "I2C" /usr/src/linux-`uname -r`/.config

I personally found there was a module in "Hardware Monitoring" (lm85) that I hadn't selected to build. Adding that fixed my similar issue.

I had the same problem an the only way I have found to solve it is to edit .config file manually

I have ensured all lines below ends with "=m" then I recompiled the kernel and installed it. (I didn't find it in the kernel config menu)

I am having the exact same problem as jmja89. sensors-detect picks up my sensors, but things still don't work. Here is an example of what I am seeing:

I have the exact same problem on an amd64 ASUS M2N-SLI Deluxe. The detected/required drivers for me is it87 and i2c_isa both are started and other i2c stuff is enabled in the kernel which is 2.6.16r9 as well...

Thanks, drescherjm.

Apart from "." and ".." there are no directories in your /sys/class/hwmon direcory, right? That's bad as sensors will look there for the devices to monitor.

Please post the output of
