'greetings Based on the output of sensors-detect I insmodded adm1021: Driver `adm1021' (should be inserted): Detects correctly: * Bus `SMBus I801 adapter at 0c00' (Algorithm unavailable) Busdriver `i2c-i801', I2C address 0x4e Chip `National Semiconductor LM84' (confidence: 5) The module was build from a 2.6.5-rc1 kernel tree (SMP). After insmodding the module the machine shut down instantly, which could have only been caused because the hardware detected _something_ critical enough that it shut down the system immediatly. Initial tries to power up again were futile, only after unplugging and giving it a few minutes the machine came back up again (*phew*). I can't give you anything other helpfull information concerning what happened, simply because there was none given. However I put the details of the machine below. Whatever happened, it shouldn't have happened :-) (I'm just glad the machine came back on again.) let me know if you require any other information Kind regards, Eric /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.40GHz stepping : 9 cpu MHz : 2400.153 cache size : 512 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 4734.97 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.40GHz stepping : 9 cpu MHz : 2400.153 cache size : 512 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 4784.12 root at pathfinder eric # sensors-detect This program will help you determine which I2C/SMBus modules you need to load to use lm_sensors most effectively. You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-i801' for device 00:1f.3: Intel 82801EB ICH5 Probe succesfully concluded. We will now try to load each adapter module in turn. Load `i2c-i801' (say NO if built into your kernel)? (YES/no): no Do you now want to be prompted for non-detectable adapters? (yes/NO): To continue, we need module `i2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. Do you want to load it now? (YES/no): no Well, you will know best. We will just hope you edited `/etc/modules.conf' for automatic loading of this module. If not, you won't be able to open any /dev/i2c-* file (unless youhave it built-in into your kernel) We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will 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. That often includes address 0x69 (clock chip).

(0x52) Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `adm1021' (should be inserted): Detects correctly: * Bus `SMBus I801 adapter at 0c00' (Algorithm unavailable) Busdriver `i2c-i801', I2C address 0x4e Chip `National Semiconductor LM84' (confidence: 5) Driver `w83781d' (may not be inserted): Misdetects: * ISA bus address 0x0290 (Busdriver `i2c-isa') Chip `Winbond W83627HF' (confidence: 8) Driver `w83627hf' (should be inserted): Detects correctly: * ISA bus address 0x0290 (Busdriver `i2c-isa') Chip `Winbond W83627HF Super IO Sensors' (confidence: 9) I will now generate the commands needed to load the I2C modules. Sometimes, a chip is available both through the ISA bus and an I2C bus. ISA bus access is faster, but you need to load an additional driver module for it. If you have the choice, do you want to use the ISA bus or the I2C/SMBus (ISA/smbus)? If you want to load the modules at startup, generate a config file below and make sure lm_sensors get started (eg. rc-update add lm_sensors default). To make the sensor modules behave correctly, add these lines to /etc/modules.conf: #----cut here---- # I2C module options alias char-major-89 i2c-dev #----end cut here---- WARNING! If you have some things 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 it's done. To load everything that is needed, execute the commands above... #----cut here---- # I2C adapter drivers modprobe i2c-i801 modprobe i2c-isa # I2C chip drivers modprobe adm1021 modprobe w83627hf # sleep 2 # optional /usr/local/bin/sensors -s # recommended #----end cut here---- Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name? (yes/NO/s): no
