Good evening,

I have a trouble with my motherbord. "My" linux kernel (2.6.18.3) don't
found thermal sensors.

Directory /proc/acpi/thermal_zone is empty, like you can see below.

I think I have tick all necessary options in the kernel

When i run mbmon, i can see my processor temperature.

I've make research about this bug, but i don't found anything.

So, do you think the probleme come from my kernel configuration ?

Not all BIOSes make the thermal zones visible through ACPI. You may just 
be unlucky in this respect.
