Hi,

(I read all threads about sensors and didn't find my answer.)

I used to get lmsensors working under kernel 2.4, but with the 2.6, I can't get it working.

I erased the previous version of lmsensors for 2.4 kernel, then I installed kernel 2.6.1 et lmsensors 2.8.3, I did 'make user' + 'make user_install', then sensors-detect.


Sensors-detect works fine and detects my chips, but, there is still a litle message 'Algorithm unavailable' and system says it can't find any sensor after reboot.

My mobo is an asus a7a266 with Ali 1533D+ chipset for the smbus.

Thanks for any help please.


Here is the result of sensors-detect:
root@PC-1-Linux:~/inet-download/lm_sensors-2.8.3
# sensors-detect

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-ali15x3' for device 00:11.0: Acer Labs 1533/1543
Use driver `i2c-ali1535' for device 00:11.0: Acer Labs 1535
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Load `i2c-ali15x3' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
Load `i2c-ali1535' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
Do you now want to be prompted for non-detectable adapters? (yes/NO):
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no):
Module loaded succesfully.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).

Next adapter: SMBus ALI1535 adapter at e800 (Algorithm unavailable)

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. Do you want to scan the ISA bus? (YES/no):

typically a bit more dangerous, as we have to write to I/O ports to do
this. Do you want to scan for Super I/O sensors? (YES/no):

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `w83781d' (should be inserted):
Detects correctly:
* Bus `SMBus ALI1535 adapter at e800' (Algorithm unavailable)
Busdriver `i2c-ali1535', I2C address 0x2d (and 0x48 0x49)
Chip `Asus AS99127F (rev.2)' (confidence: 8)


I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?

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
#----cut here----

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-ali1535
# I2C chip drivers
modprobe w83781d
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----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.

Do you want to generate /etc/sysconfig/lm_sensors? (YES/no):
Copy prog/init/lm_sensors.init to /etc/rc.d/init.d/lm_sensors
for initialization at boot time.

Have you mkdir /sys and the edited the fstab and put this line in it so the sensors will have a bus.
And you do have the W87831D & ALI1535 compiled as a modules so they are available to the system for instance with mine I need the VIA686A & I2C_ISA.

Yes I added 'sys' in fstab.
Yes I have all i2c compiled in modules.

In that case I think I'm out of ideas other than I installed 2.6.2-rc1 today and noticed there are some changes to the I2C in the changelog for both your chip and mine you may want to give it a try.

Edit: And I am still using the 2.8.2 modules and they are working fine so you may want to try them as well.

I tried the kernel 2.6.3, no way to get sensors working. Any suggestion?

A summary of the steps taken to get it working and errors encountered in the process would be a start. There is a complete lack of useful information in your post to give you any course of action to take. FWIW I am running 2.6.3 now and the sensors work fine so it is possible. Oh and the distribution you are running would be nice to know as well.
