i have spent several hours trying to figure out how to setup lm-sensors. i have slowly made progress, and was almost able to achieve complete success. i am not sure though if i made the correct steps. let me share my experience in the hope that you could help me sort this one out.
a) system
- Ubuntu Dapper
2.6.15-26-386
- compiled lm-sensors.2.10.0
- pertinent output of lspci
-------------------------
0000:00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 04)
b) pertinent output of sensors-detect
----------------------------------
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801FB ICH6
Probe succesfully concluded.
...
Next adapter: SMBus I801 adapter at 1400
Do you want to scan it? (YES/no/selectively):
Client found at address 0x08
Client found at address 0x44
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client found at address 0x50
Probing for `SPD EEPROM'... Success!

Probing for `DDC monitor'... Failed!

#----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-i801
# I2C chip drivers
modprobe eeprom
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----
c) the following modules were loaded:
$ lsmod |grep i2c
i2c_dev 9984 0
i2c_i801 9100 0
i2c_core 21904 2 eeprom, i2c_dev,i2c_i801
problem started when i used "sensors". the results came out as
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!
c) i tried playing around with i2cdump using the addresses of devices i got with "sensors-detect"
c1) results of "i2cdump 0x08"

d) i tried to guess what chip/device to use. i experimented with adm1021:
d1) modprobe adm1021 force=0,0x08
"sensors" give:
max1617-i2c-0-08
Adapter: SMBus I801 adapter at 1400
Board: -1?C (low = -1?C, high = -1?C) ALARM (LOW,HIGH)
CPU: -1?C (low = -1?C, high = -1?C) ALARM (N/A,LOW,HIGH)
d2) modprobe adm1021 force=0,0x44; "sensors" give
lm84-i2c-0-44
Adapter: SMBus I801 adapter at 1400
Board: +0?C (low = +0?C, high = +0?C)
CPU: +0?C (low = +0?C, high = +0?C)
d3) modprobe adm1021 force=0,0x50; "sensors" give
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!
d4) same results with modprobe adm1021 force=0x052
d5) modprobe adm1021 force=0,0x69
max1617-i2c-0-69
Adapter: SMBus I801 adapter at 1400
Board: +15?C (low = +15?C, high = +15?C)
CPU: +15?C (low = +15?C, high = +15?C) ALARM (N/A,LOW)
This last seem to be the closest. But for sure, it gives me incorrect information (15?C for CPU!)...
Am I doing the right thing?
I wish someone could help. Thanks!
