Re: [lm-sensors] LPC47M192-NC Fans

Thanks for your assistance.

Please find the requested information below: output of sensors-detect,
/proc/ioports and the kernel log entry after attempting to load smsc47m1

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 82801DB ICH4

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 1880 (i2c-0)
Do you want to scan it? (YES/no/selectively): Client found at address 0x2d
Handled by driver `smsc47m192' (already loaded), chip type `smsc47m192'
Client found at address 0x50
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 Yes
     (confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'...                                No
Client found at address 0x51
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 Yes
     (confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'...                                No

Next adapter: intel drm CRTDDC_A (i2c-1)
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'...                                Yes
     (confidence 8, not a hardware monitoring chip)

Next adapter: bt878 #0 [sw] (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'...                                No

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'...                   No
Trying family `SMSC'...                                     Yes
Found `SMSC LPC47M15x/192/997 Super IO Fan 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...                         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 `smsc47m192' (should be inserted):
   Detects correctly:
   * Bus `SMBus I801 adapter at 1880'
     Busdriver `i2c-i801', I2C address 0x2d
     Chip `smsc47m192' (confidence: 6)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 
To load everything that is needed, add this to /etc/modules:

#----cut here----
# I2C adapter drivers
i2c-i801
# Chip drivers
smsc47m192
#----cut here----

Do you want to add these lines automatically? (yes/NO)
