correctness of hw.sensors, lm

[Christian Gut <cycloon@is-root.org>]

Hi,


I just have the problem that lm0 shows wrong values for the cpu-temp:

hw.sensors.10 = lm0, Temp2, temp, 77.49 degC / 171.48 degF

but bios shows 40 degC. Temp1 and Temp3 _seem_ to show correct values.
Is there any possibility or need to adjust these values or offsets or
something? I know of the need to calibrate sensors in lm_sensors under
linux, but i did not find anything like that in the documentation of lm, sysctl.

Im running OpenBSD 3.4 -stable, with all patches applied, dmesg below [1].

If i missed something or there is any documentation i should read,
please point me to it.

thx,

	Christian Gut
