has anone goten lm_sensors to work under the 2.4 or 2.6 kernel?

The linux install guide says...

"The SMBus is the hardware sensors bus, this is were the sensors of your motherboards reports to, like temperature, fans states, ram states etc ...Honestly i haven't fool around them yet, but will very soon."

I donot see SMBus anywhere when I do an lspci...

I am assuming that it is the i2c-core and i2c-i801 modules I need.

I have a 8887 and am using gentoo with the mm-sources (2.6) and can't seem to get any sensors detected.

does lm_sensors actually work on a sager? If so could someone post their i2c section of their .config.

thx,

Since these sensors are used to monitor HW and since ACPI works pretty well on the Sagers I am not sure why you would want to use these.

acpi

i'm trying to monitor fan speed and cpu temp...was going to use gkrellm2 with acpi but gkacpi2-.4 seg faults and the .5 from 'emerge gkacpi' only shows battery life. acpi is not showing anything in /proc/acpi/fan/ or /proc/acpi/thermal_zone/.

so I was going to resort to lm_sensors...but that is not working either.

how can i monitor fan speed and cpu temp on a sager?

Make sure that you have all the ACPI modules loaded. I strongly suggest the 2.6 kernel. If you dont have the modules loaded then there will be nothing in /proc/acpi. I monitor CPU temp, fan state , battery etc all through ACPI. I do not believe it is possible to monitor fan speed with it.

where

yes I have eveything compiled in and am using the 2.6 kernel. Where do you see cpu temp and fan state?

Usually under the /proc/acpi dir - now keep in mind I am running a 5680 and the MB etc is quite different between the 8887 and the 5680 so you may have to tweak your dsdt file to handle your MOBO. Dont ask me how to do it because I dont know - but there are quite a few sites that do and you can google for them.
