6 Detection (see below) seems to proceed correctly.
7 Modules are loaded.  The "sensors" command complains:
8
9 [jhg@athena ~]$ sudo sensors -s
10 No sensors found!
11 Make sure you loaded all the kernel drivers you need.
12 Try sensors-detect to find out which these are.

86 This program will help you determine which kernel modules you need
87 to load to use lm_sensors most effectively. It is generally safe
88 and recommended to accept the default answers to all questions,
89 unless you know what you're doing.
90
91 We can start with probing for (PCI) I2C or SMBus adapters.
92 Do you want to probe now? (YES/no):
93 Probing for PCI bus adapters...
94 Use driver `i2c-i801' for device 0000:00:1f.3: Intel ICH8
95
96 We will now try to load each adapter module in turn.
97 Module `i2c-i801' already loaded.
98 If you have undetectable or unsupported adapters, you can have them
99 scanned by manually loading the modules before running this script.
100
101 We are now going to do the I2C/SMBus adapter probings. Some chips may
102 be double detected; we choose the one with the highest confidence
103 value in that case.
104 If you found that the adapter hung after probing a certain address,
105 you can specify that address to remain unprobed.
106
107 Next adapter: SMBus I801 adapter at 2000
108 Do you want to scan it? (YES/no/selectively):
109 Client found at address 0x08
110 Client found at address 0x30
111 Client found at address 0x32
112 Client found at address 0x44
113 Probing for `Maxim MAX6633/MAX6634/MAX6635'...              No
114 Client found at address 0x50
115 Handled by driver `eeprom' (already loaded), chip type `eeprom'
116 Client found at address 0x52
117 Handled by driver `eeprom' (already loaded), chip type `eeprom'
118 Client found at address 0x69
119
120 Some chips are also accessible through the ISA I/O ports. We have to
121 write to arbitrary I/O ports to probe them. This is usually safe though.
122 Yes, you do have ISA I/O ports even if you do not have any ISA slots!
123 Do you want to scan the ISA I/O ports? (YES/no):
124 Probing for `National Semiconductor LM78' at 0x290...       No
125 Probing for `National Semiconductor LM78-J' at 0x290...     No
126 Probing for `National Semiconductor LM79' at 0x290...       No
127 Probing for `Winbond W83781D' at 0x290...                   No
128 Probing for `Winbond W83782D' at 0x290...                   No
129 Probing for `Winbond W83627HF' at 0x290...                  No
130 Probing for `Silicon Integrated Systems SIS5595'...         No
131 Probing for `VIA VT82C686 Integrated Sensors'...            No
132 Probing for `VIA VT8231 Integrated Sensors'...              No
133 Probing for `AMD K8 thermal sensors'...                     No
134 Probing for `IPMI BMC KCS' at 0xca0...                      No
135 Probing for `IPMI BMC SMIC' at 0xca8...                     No
136
137 Some Super I/O chips may also contain sensors. We have to write to
138 standard I/O ports to probe them. This is usually safe.
139 Do you want to scan for Super I/O sensors? (YES/no):
140 Probing for Super-I/O at 0x2e/0x2f
141 Trying family `ITE'...                                      Yes
142 Found unknown chip with ID 0xf191
143 Trying family `National Semiconductor'...                   Yes
144 Found unknown chip with ID 0xf191
145 Trying family `SMSC'...                                     Yes
146 Found unknown chip with ID 0xf191
147 Trying family `VIA/Winbond/Fintek'...                       Yes
148 Found unknown chip with ID 0xf191
149 Probing for Super-I/O at 0x4e/0x4f
150 Trying family `ITE'...                                      No
151 Trying family `National Semiconductor'...                   No
152 Trying family `SMSC'...                                     No
153 Trying family `VIA/Winbond/Fintek'...                       No
154
155 Now follows a summary of the probes I have just done.
156 Just press ENTER to continue:
157
158 Driver `eeprom' (should be inserted):
159   Detects correctly:
160   * Bus `SMBus I801 adapter at 2000'
161     Busdriver `i2c-i801', I2C address 0x50
162     Chip `eeprom' (confidence: 6)
163   * Bus `SMBus I801 adapter at 2000'
164     Busdriver `i2c-i801', I2C address 0x52
165     Chip `eeprom' (confidence: 6)
166
167   EEPROMs are *NOT* sensors! They are data storage chips commonly
168   found on memory modules (SPD), in monitors (EDID), or in some
169   laptops, for example.
170
171 I will now generate the commands needed to load the required modules.
172 Just press ENTER to continue:
173
174 To make the sensors modules behave correctly, add these lines to
175 /etc/modules.conf:
176
177 #----cut here----
178 # I2C module options
179 alias char-major-89 i2c-dev
180 #----cut here----
181
182 To load everything that is needed, add this to some /etc/rc* file:
183
184 #----cut here----
185 # I2C adapter drivers
186 modprobe i2c-i801
187 # Chip drivers
188 modprobe eeprom
189 # sleep 2 # optional
190 /usr/bin/sensors -s # recommended
191 #----cut here----
192
193 If you have some drivers built into your kernel, the list above will
194 contain too many modules. Skip the appropriate ones! You really
195 should try these commands right now to make sure everything is
196 working properly. Monitoring programs won't work until the needed
197 modules are loaded.
198
199 Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):
200
201 ***** i2cdetect *****

203 [jhg@athena ~]$ sudo i2cdetect -l
