[lm-sensors] No sensors found >2.6.21, w83627hf, ICH6

[lm-sensors] No sensors found >2.6.21, w83627hf, ICH6

[Stefan Sassenberg]

Hello,

I have a problem making lm-sensors work on my system. It's a slightly 
old debian where I updated some packages and now use sensors and 
libsensors of version 2.9.1. I used to run a 2.6.21 kernel where sensors 
finds some chip and also shows fan speed and temperature values.

Then I upgraded the kernel to a 2.6.23 and always get the error message 
"No sensors found". The board is an MSI board and it has an 82801 ICH6 
chipset.

sensors-detect advises me to modprobe w83627hf, which I do, but the 
result is the above.

I installed a gentoo on the same machine, where it worked, and made an 
lsmod, which showed w83627hf, hwmod and hwmon_vid. I took the kernel 
config file and applied it to the kernel from kernel.org to build the 
same kernel for my debian. I modprobed the very same modules but failed. 
What can I do to find the solution?

Thank you.

Stefan

"some chip" doesn't tell us much... Can you please provide the complete
output of "sensors"?

What is the exact motherboard model?

Any message in the kernel logs when you modprobe w83627hf? Does the
modprobe itself fail or succeed? If it fails, what's the error message?

What kernel is your gentoo system running?

> What can I do to find the solution?

Please compare /proc/ioports between a system where the w83627hf driver
works for you and a system where it doesn't. I'd suspect a resource
conflict.

When I modprobe, a line is added to /var/log/dmesg:
w83627hf: Found W83627THF chip at 0x290
There's no message on stdout or stderr.

Using the 2.6.21.5 kernel:
0295-0296 : pnp 00:09
   0295-0296 : w83627hf

Using the 2.6.23.14 kernel:
Before modprobing:
...
0295-0296 : pnp 00:09
...

After modprobing:
...
0295-0296 : w83627hf
   0295-0296 : pnp 00:09
     0295-0296 : w83627hf

So the kernel itself seems to be happy...

And this looks OK as well. My first guess was wrong, let me suggest
something else...

I didn't notice at first but you wrote you were using lm-sensors 2.9.1.
That's pretty old. In kernel 2.6.22 the w83627hf driver was converted
from an i2c-isa driver to a platform driver (together with many other
hwmon driver, as we were finally getting rid of i2c-isa.) Support for
platform drivers was added to lm-sensors only in 2.10.0. So, no
surprise it doesn't work for you. For a kernel >= 2.6.22, I would even
recommend lm-sensors >= 2.10.3.

Very good. I could download deb packages of version 2.10.1. The next 
version is 2.10.5 but there seem to be no lmsensors package of that 
version for now. But now I get results:

Thank you very much, Jean. My next problem are the strange values, but I 
haven't read the manuals regarding that point yet.

The voltages look rather good to me, but you should compare with what
the BIOS says for confirmation. The limits are wrong but that's
expected - set them in /etc/sensors.conf and run "sensors -s" to write
them to the chip.

No fan speeds, strange, unless you have no fans on that systems, or
very very slow fans (in which case you should increase the fan_div
values to 16 or even 32.) Are there fan speeds displayed in the BIOS?

Temperatures look wrong, -48 typically means no sensor connected,
+108.5°C is too high to be realistic unless your computer case is on
fire ;) Try changing the thermal sensor types... although the BIOS
should have set them up right.

The lack of fan speeds and proper temperature readings might hint at an
additional sensor chip on your board. If you can't get them out of the
W83627THF, try running an up-to-date version of sensors-detect and see
if it finds an extra chip on the SMBus.

Yes, no problem.

Fans have speed 1365rpm and 2396rpm resp. according to BIOS. Higher divs 
aren't working either, but that's ok, fan speeds are no must at present.

Bad news for me:

Probing for `Analog Devices ADT7467 or ADT7468'...          Success!
     (confidence 7, driver `to-be-written')

No driver yet and nobody working on it as far as I know - but in the
meantime you may try forcing the lm85 driver, with chip type adm1027,
you should get some basic results.

After modprobing w83627hf, lm85, adm1021, adm1025, adm1026, adm1029, 
adm1031 the results are just the same.

Meanwhile I connected the hard disk to a MSI W7231IMS. It has the same 
AD chip:
Probing for `Analog Devices ADT7467 or ADT7468'...          Success!
...but a different Winbond:
Found `Winbond W83627EHF/EHG Super IO Sensors'              Success!
...and shows no fan speed but three temperature values:
Sys Temp:    +33°C  (high =   +45°C, hyst =   +40°C)
CPU Temp:  +33.0°C  (high = +45.0°C, hyst = +40.0°C)
temp3:     +32.5°C  (high = +80.0°C, hyst = +75.0°C)

Not bad.

Huu, that's not what I suggested. Leave the adm1021, adm1025, adm1026,
adm1029 and adm1031 drivers alone, they won't work for you. Instead,
try loading the lm85 driver that way:

modprobe lm85 force_adm1027=0,0x2e

The exact parameter depends on the I2C bus and address where
sensors-detect found the ADT7467/8 chip. The above is for bus i2c-0,
address 0x2e. Adjust the command if the bus number or the chip address
differ on your system.

As you are using lm-sensors 2.10.1 with a recent kernel, it is possible
that libsensors won't work properly with the forced ADM1027 chip, but
at least you should be able to read some temperature values directly
from /sys/class/hwmon.

Yep, these temperatures look reasonable.

Well, in that case, I think I have to consider that mainboard type 
unsupported. Of course, the offer persists. :-)
