LM_Sensors

[tinkergnome]

Not sure exactly which forum this needs to go in as it has a bit of everything in it.
I am running Gentoo Linux with a 2.6.36-gentoo-r5 Kernel. I have Dual AMD 265 Opteron's on a Tyan S2882-d Mainboard.

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.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No

    (driver `k8temp')

VIA Nano thermal sensor...                                  No

Some Super I/O chips contain embedded 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 0x2e/0x2f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               Yes
Found `Winbond W83627HF/F/HG/G Super IO Sensors'            Success!
    (address 0x290, driver `w83627hf')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No

Trying family `ITE'...                                      No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are 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):

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-amd756' for device 0000:00:07.3: AMD-8111 ACPI
FATAL: Module i2c_amd756 not found.
Failed to load module i2c-amd756.
Using driver `i2c-amd8111' for device 0000:00:07.2: AMD-8111 SMBus 2.0
FATAL: Module i2c_amd8111 not found.
Failed to load module i2c-amd8111.
FATAL: Module i2c_dev not found.
Failed to load module i2c-dev.

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

Driver `w83627hf':
  * ISA bus, address 0x290
    Chip `Winbond W83627HF/F/HG/G Super IO Sensors' (confidence: 9)

Driver `k8temp':
  * Chip `AMD K8 thermal sensors' (confidence: 9)

Warning: the required module w83627hf is not currently installed
on your system. If it is built into the kernel then it's OK.
Otherwise, check ww.lm-sensors.org/wiki/Devices]Devices ? lm-sensors for
driver availability.

Warning: the required module k8temp is not currently installed
on your system. If it is built into the kernel then it's OK.
Otherwise, check ww.lm-sensors.org/wiki/Devices]Devices ? lm-sensors for
driver availability.

No modules to load, skipping modules configuration.

I am unable to load the drivers as modules using insmod

insmod example
<codeinsmod k8temp
insmod: can't read 'k8temp': No such file or directory

I have compiled the drivers as a module in the kernel and as built-in and i always get the same response from sensors-detect

any help would be greatly appreciated let me know if you need any more information

Hello and Welcome.
The best docs for lmsensors is
lm-sensors
and
Lm sensors - Gentoo Linux Wiki

Most sensors do not have drivers written for them as yet. You are lucky in that a couple of the important ones are recognized and supported! On my system, an Intel S5000XVN dual processor workstation/server motherboard, none of the on-board sensors are supported with RHEL/CentOS 5.x. I am hoping for better luck with 6.0, but CentOS 6 isn't out yet, and I am only testing Scientific Linux 6 (another RHEL clone) in a virtual machine.
