LinuxQuestions.org - Conky - sensors-detect > modprobe i2c-nforce2 > WARNING: Error inserting i2c

I have installed lm_sensors-2.10.3-i486-1.tgz successfully, but can not
read system temp and fan in Conky system monitor. I have had this
problem before. I think it had something to do with the "linking" of
kernel source info, but I can't find the solution again. Can anyone help
me?

Here are my sensors-detect, modprobe, sensors, lsmod, and grep dmesg
logs:

1. Sensors-Detect Log:

# sensors-detect

# sensors-detect revision 4348 (2007-03-18 02:45:21 -0700)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-nforce2' for device 0000:00:01.1: nVidia Corporation
nForce4 SMB
us (MCP)

We will now try to load each adapter module in turn.
Module `i2c-nforce2' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no):
WARNING: Error inserting i2c_core
(/lib/modules/2.6.21.5-smp/kernel/drivers/i2c/
i2c-core.ko): Invalid module format
Module loaded successfully.

We are now going to do the I2C/SMBus adapter probings. Some chips may
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.

Next adapter: NVIDIA i2c adapter 2 at 1:00.0 (i2c-4)
Do you want to scan it? (YES/no/selectively):

Next adapter: NVIDIA i2c adapter 1 at 1:00.0 (i2c-3)
Do you want to scan it? (YES/no/selectively):

Next adapter: NVIDIA i2c adapter 0 at 1:00.0 (i2c-2)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x50
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... No
Probing for `EDID EEPROM'... Success!
(confidence 8, driver `eeprom'), other addresses: 0x51 0x52 0x53
0x54 0x55 0

Probing for `Maxim MAX6900'... No

Next adapter: SMBus nForce2 adapter at 4c40 (i2c-1)
Do you want to scan it? (YES/no/selectively):

Next adapter: SMBus nForce2 adapter at 4c00 (i2c-0)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x50
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'...
Success!
(confidence 8, driver `eeprom')
Probing for `EDID EEPROM'... No
Probing for `Maxim MAX6900'... No
Client found at address 0x51
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'...
Success!
(confidence 8, driver `eeprom')

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no): Probing for `National
Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM78-J' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Probing for `Silicon Integrated Systems SIS5595'... No
Probing for `VIA VT82C686 Integrated Sensors'... No
Probing for `VIA VT8231 Integrated Sensors'... No
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): Probing for
Super-I/O at 0x
2e/0x2f
Trying family `ITE'... Yes
Found `ITE IT8712F Super IO Sensors' Success!
(address 0x290, driver `it87')
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `ITE'... No
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No

Some CPUs or memory controllers may also contain embedded sensors.
Do you want to scan for them? (YES/no):
AMD K8 thermal sensors... Success!
(driver `k8temp')
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No

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

Driver `eeprom' (should be inserted):
Detects correctly:
* Bus `NVIDIA i2c adapter 0 at 1:00.0'
Busdriver `UNKNOWN', I2C address 0x50 (and 0x51 0x52 0x53 0x54 0x55
0x56 0x5
7)
Chip `EDID EEPROM' (confidence: 8)
* Bus `SMBus nForce2 adapter at 4c00'
Busdriver `i2c-nforce2', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus nForce2 adapter at 4c00'
Busdriver `i2c-nforce2', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)

EEPROMs are *NOT* sensors! They are data storage chips commonly
found on memory modules (SPD), in monitors (EDID), or in some
laptops, for example.

Driver `it87' (should be inserted):
Detects correctly:
* ISA bus, address 0x290
Chip `ITE IT8712F Super IO Sensors' (confidence: 9)

Driver `k8temp' (should be inserted):
Detects correctly:
* Chip `AMD K8 thermal sensors' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue:

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 unknown adapter NVIDIA i2c adapter 0 at 1:00.0
# modprobe unknown adapter NVIDIA i2c adapter 1 at 1:00.0
# modprobe unknown adapter NVIDIA i2c adapter 2 at 1:00.0
modprobe i2c-nforce2
# Chip drivers
modprobe eeprom
modprobe it87
modprobe k8temp
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#----cut here----

If you have some drivers 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 the needed
modules are loaded.

Do you want to generate /etc/sysconfig/lm_sensors? (yes/NO):
