lm-sensors on Asus A8N-E (SOLVED)

[bernt]

Hello,

I have a problem getting lm-sensors to work on my system (Asus A8N-E / AMD 64 2800+)
My kernel version is: 2.6.11-gentoo-r3

In this kernel al the needed modules should be already there, I double-checked this and they are.
To install lm-sensors I did:

* emerge I2C LM_Sensors
* sensors-detect
this worked fine, IT87 was detected.

I loaded all the required modules (checked with lsmod), no problem so far.

No when I run sensors my output is:
_____________________________________
it8712-isa-0290
Adapter: ISA adapter
_____________________________________

and that's it

the only thing dmesg says is:

______________________________________
it87: Found IT8712F chip at 0x290, revision 7
i2c /dev entries driver
it87: Found IT8712F chip at 0x290, revision 7
______________________________________

please help!?

[apmurray]

Firstly you do not need the lm_sensors or i2c packages installed to use the sensors, as as you said yourself, the kernel already has the modules, you just need to know which ones to build and then load (however the sensors program comes with lm_sensors IIRC).
Perhaps there is some conflict between the kernel i2c modules and the ones from the i2c package so try unmerging the i2c package first.
Have you loaded the i2c-isa module as I think this will probably be needed...
Sorry I can't be of more help, I am not familiar with the A8N-E mobo.

[bernt]

Thanks for your reply. I unemerged the i2c package and restarted lm-sensors. The modules I need as far as I know
are loaded (including i2c-isa). The result is still the same.

The weird thing is that I don't get any errors, dmesg/logfiles, but maybe I do get errors except that I don't know
where they're logged.

I suspect that the reason that I don't get any output is because there's some module I need to load that is mobo
specific and I don't know about it.

Thanks for your help anyway! Hopefully there's somebody with the same mobo and got it working

[s0be]

This leads me to believe you need to use:

the isabus driver (i2c-isa)
the lm87 driver (it87)

[bernt]

Thanks for you reply.

That's correct. That's also what sensors-detect tells me. However, these modules are loaded but there's no output.

[razorback]

I have the same MB and sensors gives me the same output. But all the sensor readings are there. Check out /sys/class/i2c-dev/i2c-0/device/0-0290/ . The following modules are loaded:
i2c-dev
i2c-isa
i2c-sensors
i2c-core
it87
I am running gentoo-sources -2.6.11-r11. I use gkrellm in kde and it reads all the sensors. I do know that sensors worked at one time in the past with this MB.

[bernt]

So you do have output in gkrellm? I don't have x installed (server-system) so installing gkrellm is not very useful...

I checked /sys/class/i2c-dev/i2c-0/device/0-0290/ but what can I do with the information here? Are these output values (?) cause they look like config values.

I am glad you know that it should work with this mobo, now it's just a matter of how to make it work

[fly-a-lot]

bernt,

looks like I had exactly the same problem with my A8N-E a few days ago. After going almost crazy with this problem it suddenly worked. However, I'm not sure what ultimately did the trick, but maybe we can work that out.

Before it started to work for me, I did a few modifications. So I cant't tell you what actually did the trick.

1. Let's start with .config:
- In my case CONFIG_I2C=y and CONFIG_I2C_CHARDEV=y (but I doubt it makes a difference if you load the modules instead)
- everything else related to I2C and the sensors are configured as modules

2. I emerged lm_sensors-2.9.1 (sys-apps/lm_sensors ~amd64 required in /etc(portage/package.keywords)
don't ask me if that makes any difference, but I tried that a few hours before lm_sensors started to work)

3. I updated the BIOS. My mainboard came with version 1003. I updated to 1006-003 (the latest beta version)
again, not sure if that solved the problem. Just reporting what I did that morning

OK, after bootimg the kernel (from step 1) I did the following routine
a. run sensors-detect
b. modprobe the required modules
c. run sensors -s
d. run sensors -> and suddenly it worked

Good luck!!!
I hope I didn't forget anything of importance.
If you happen to find out what actually cured the problem, please let us know.

[fly-a-lot]

Oh, I forgot to mention that the readings of lm_sensors are not correct right out of the box.
Some Voltages and also the CPU temperature are obviously mixed. But that can be changed manually...

[razorback]

Try a later version of lm_sensors. No sensors output with 2.8.7 but seems to work with with 2.9.1.

[bernt]

thanks for your replies!

I am trying to install the 'masked' package lm_sensors-2.9.1 but having some problems circumventing the masked
property....

@fly-a-lot

If I get the masked package installed I will try again and then follow step by step what you did to determine what the crucial step is. The bios-update I'll have to do later since I'm not at home right now. Anyway I will let you know what the result is. Thanks!

[fly-a-lot]

I am trying to install the 'masked' package lm_sensors-2.9.1 but having some problems circumventing the masked
property....

I can't recall doing anything else like
echo "sys-apps/lm_sensors ~amd64" >> /etc/portage/package.keywords
emerge --update lm_sensors
(or something close to that)

Good luck, bernt!

[razorback]

I run two installations of Gentoo on my A8N-E. One is x86 and the other is ~amd64. The x86 uses lm_sensors-2.8.7 and the ~amd64 uses lm_sensors-2.9.1. Sensors works with 2.9.1 but not with 2.8.7. The BIOS is 1004. I would put the following in /etc/portage/package.keywords: sys-apps/lm_sensors ~amd64.

[bernt]

Succes!!

I unemerged lm_sensors. Then I put the "sys-apps/lm_sensors ~amd64" in /etc/portage/package.keywords,
afterwards I emerged lm_sensors-2.9.1, ran sensors-detect, loaded modules, sensors -s, sensors and then it
worked!!

Thank you very much fly-a-lot and razorback, you guys made my day

@fly-a-lot: I think it's save to conclude the problem was the version of lm_sensors that did the trick. The one thing I didn't check is my bios-version, it might be the latest version cause I just got this mobo which is the new revision (different chipset fan...mine died last week). If you want, I can check it for you, I'll just have to hookup a monitor and kb to it.
It also looks like the sensor values are correct:

temp1: +40 C (low = -1 C, high = -1 C) sensor = thermistor
temp2: +42 C (low = -1 C, high = -1 C) sensor = thermistor
temp3: +25 C (low = -1 C, high = -1 C) sensor = thermistor

I'll will check it further....

[fly-a-lot]

Excellent, bernt, glad to hear you were successful!

Looks like you are only missing the right /etc/sensors.conf now. Maybe you have to unemerge lm_sensors once again, delete that file and emerge it again.

Good to know it was the lm_sensors version which has to be blamed. I hope it will save other people time to be able to look it up now.

@everybody with an A8N-E Mainboard:
As suggested by razorback and proved by bernt: You wiill need to emerge (at least) lm_sensors-2.9.1 !!!

Enjoy and good luck, bernt!

Hello,

my sensors does not work! I am using lm_sensors 2.92 with kernel 2.6.14-gentoo-r4.
lm-sensors only detects i2c-nforce2 and eeprom. What's wrong?

(~amd64)

[fly-a-lot]

Well, Treito, you should make it a habit to provide more information if you request help. You didn't even say if you are just installing lm-sensors or if it worked before. Anyway, I have a similar configuration, except that I'm using kernel-2.6.14-gentoo-r2 - and that works.

Assuming you are just installing lm_sensors, did you carefully read this thread? Better double check your /usr/src/linux/.config file. You need the following i2c/sensor stuff to be included in the kernel or loaded as modules:
i2c-dev
i2c-isa
i2c-sensors
i2c-core
it87

[Treito]

I have compiled the whole ic and sensors stuff as module.
lm_sensors have not ever been worked on my computer.
Which informations do you need?

If you change config, don't forget to "make && make modules_install", copy all the relevant stuff to /boot and reboot the computer.

Then

Code: Select all

modprobe i2c-core
modprobe i2c-dev
modprobe i2c-isa
modprobe it87
lsmod

You shoud find i2c_dev, i2c_core, i2c_isa, it87
Otherwise double check .config and check the output of dmesg.

[Treito]

Okay once again, the modules are loaded but I found no sensors!
It's a little bit weird because of running Gentoo 2.6.13-r4 sensors detects a chip of my TV-card, with kernel 2.6.14-gentoo-r4 no sensors are detected.

Oh sorry, looks like I misunderstood you.

Would it be a problem for you to emerge kernel 2.6.14-r2 (gentoo-sources)? It's the current stable version of gentoo-sources for the AMD64.
That one definitely works with lm_sensors-2.9.2, at least on my machine.

[fly-a-lot]

Maybe you should try one more thing (since we know the results for the Asus A8N-E mainboard):

add the following lines to /etc/modules.conf:

Code: Select all

# I2C module options
alias char-major-89 i2c-dev

Create file /etc/conf.d/lm_sensors with the following contents

Code: Select all

LOADMODULES=yes
INITSENSORS=yes
MODULE_0=i2c-isa
MODULE_1=it87

then execute

Code: Select all

modprobe i2c-core
modprobe i2c-dev
modprobe i2c-isa
modprobe it87

With lsmod make sure they are loaded. Then

Code: Select all

sensors -s

I'm not sure if the change in modules.conf needs a reboot or something. So if it doesn't work try again after rebooting.

[Treito]

With kernel 2.6.14-gentoo-r4 lm-sensors is not able to detect any chips! So I have to give -r2 a try!
2.6.13-gentoo-r4 detects the chip of my tv-card.
By the way, I have no module i2c-core and no kernel option for this module.

Sorry, no chips were detected.
Either your sensors are not supported, or they are
connected to an I2C bus adapter that we do not support.
See doc/FAQ, doc/lm_sensors-FAQ.html, or
http://www2.lm-sensors.nu/~lm78/cvs/lm_ ... s-FAQ.html
(FAQ #4.24.3) for further information.
If you find out what chips are on your board, see
http://secure.netroedge.com/~lm78/newdrivers.html for driver status.

Edit: 2.6.14-gentoo-r2 the same problem! BIOS version 1003

Edit2: It's mad. I updated to version 1010 and still the same problem. But I recognized immediatly after loading it87 I could not detect any senors anymore.

Code: Select all

To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----end cut here----

WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
To load everything that is needed, execute the commands above...

#----cut here----
# I2C adapter drivers
modprobe i2c-nforce2
# modprobe unknown adapter B2C2 FlexCop device
# modprobe unknown adapter saa7134[0]
# I2C chip drivers
modprobe eeprom
# sleep 2 # optional
/usr/bin/sensors -s # recommended

Edit 3: The module "hwmon" which is needed by it87 kills my detection of the sensors! How could I fix this?

[fly-a-lot]

hwmon runs on my system, too. And it doesn't interfere.
However, the hwmon is kind of new. I actually see it the first time. Not sure if this is new in 2.6.14 or if it was there in 2.6.12-r5 and 2.6.13-r3.

By the way, I have no module i2c-core and no kernel option for this module.

That's OK. Take a look at my settings in the .config file from above.

Did you try the procedure I described in my last post?

You know, your problems are looking quite familiar to me (see my first post in this thread). When I installed lm-sensors the first time I had about the same problems for a few days and was close to give up. Same stuff with nforce2 detected, no it87 found and so on. I never found out what was actually going wrong at that time. That's the reason why I recommend to try with my settings, to recompile the kernel accordingly and to try with the procedure described above.

I remember that I was completely surprised that the first command, which actually worked, was "sensors -s" and not "sensors-detect". After modprobing everything needed by hand, of course. I also remember that I started to remove some of modules which aren't used anyway from the .config file and recompiled the kernel over and over again. Surprisingly everything started to work at a given point. I even updated my BIOS, just like you did (see my first post in this thread).

[Treito]

Hello,

/etc/conf.d/lm_sensors is only needed when you run lm_sensors as daemon so I did not edit this file.
I changed some options as I complied kernel-2.6.14-gentoo-r2. now I have i2c_core and hwmon as module not compiled in as earlier.

I tested your procedure as described above an then sensors -s does not work anymore. I even unloaded tv-stuff and removed the other i2c-drivers, which where automatically loaded.

2.6.13-gentoo-r4 does not work either, but there I can use hwmon.

hwmon is the core-module for it87. Without hwmon you do not have any support for it87.
