i2c-i801 (No sensors found)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I'm trying to get sensors working on a motherboard I have (see details below)
I have run sensors-detect (see output further below) - and it says that
I have a i801 chipset, but when I run sensors I get this output: "No
sensors found!"

My kernel is 2.6.16.46-0.12-smp on a SUSE x86 machine

King Regards

JP

# sensors-detect revision $Revision$

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-i801' for device 0000:00:1f.3: Intel Enterprise
Southbridge - ESB2

We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

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: SMBus I801 adapter at 0440 (i2c-0)
Do you want to scan it? (YES/no/selectively):
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 `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 0x2e/0x2f
Trying family `National Semiconductor'...                   Yes
Found `Nat. Semi. PC87427 Super IO Fan Sensors'
    (but not activated)
Found `Nat. Semi. PC87427 Super IO Health Sensors'
    (but not activated)
Found `Nat. Semi. PC87427 Super IO Health Sensors'
    (but not activated)
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      No

Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no): Silicon
Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         Success!
    (driver `to-be-written')
VIA C7 thermal and voltage sensors...                       No

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)

Driver `to-be-written' (should be inserted):
  Detects correctly:
  * Chip `Intel AMB FB-DIMM thermal sensor' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):
