I have built and installed the srpm for lm_sensors2.8.7-1 from development on my Fedora Core 2 box running the linux 2.6.7-1.494.2.2smp kernel. While it works (after modifying the /etc/init.d/lm_sensors per the bugzilla report), I am puzzled about the output on my Tyan Tiger 7505 motherboard. I used the recommended approach of running sensors-detect program to identify those modules I needed to load. This gave me a /etc/sysconfig/lm_sensors of... MODULE_0=i2c-i801 MODULE_1=i2c-isa MODULE_2=w83781d MODULE_3=w83627hf However the sensors output shows two sections. One is for w83627hf-isa-0c00 and contains actual nonzero values for the temperatures and fan speeds. The second is for w83627hf-i2c-0-2d and contains only zeros for the temperature and fan speed. The first table is marked as Adapter: ISA adapter whereas the second with zero values is marked SMBus I801 adapter. What is the rational for which adapter gets the temperature measurements? Oh, this is for a dual Xeon box. Thanks in advance for any clues. Jack ps I am mucking with lm_sensors so I cam monitor my cpu temperature during molecular dynamics LAM runs.
