I downloaded lm_sensors2 from cvs on 04/24/04 at around 7:30 EST. It
compiled and installed successfully on a 2.4.26 kernel with i2c 2.8.4.
The sensors-chip driver for my pc87366 was detected by sensors-detect
and I can now see output from the driver using gkrellm or by output from
"sensors". (Full output at the end of document)
My BIOS only displays sensor information about my 2 fans and the
temperature of my cpu. The fan sensors are accurate, but the I do not
understand the temperature readings.
Bios reports cpu fan speed of between 3614 and 3840 rpm; sensors reports
fan 1 to be 3750 rpm
Bios reports case fan to be 2194 rpm; sensors reports 2142 rpm
Oddity: Running pwmconfig will restart both my fans correctly, but
reports that "fan has not returned to speed". Rerunning sensors states
that there is an overflow, and the rpm is reported to be -1. Also, I
only have 2 fans controlled by this nat.semi. chip, but pwmconfig speaks
strangely of 3 fans, and controllers overlapping. (Output of pwmconfig
at end of document).
As for temperatures, I am not certain how they are to be read. I do not
think they are getting updated. Both the closed case and open case
reveal the exact same temperature (according to gkrellm). I am not sure
how to use the offset or factor, or how to determine what really is my
temperature before using those to adjust the numbers.
Here is output of sensors (before pwmconfig):

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!

If possible, I would like to know if the temperature readings are a bug
or if there is way to adjust them to display correct temperatures (my
bios never reads more than about 130 degrees fahrenheit or about 55
degrees celcius).
Thanks!
