[lm-sensors] seeking a W83687THF patch for 2.6.15 (re: ticket

Hi Steven,

Most probably your CPU Core voltage. Is it correct? What's your CPU?

> in1: +1.52 V (min = +2.54 V, max = +2.11 V) ALARM

I'd guess this is the AGP voltage (nominal is +1.5V).

> in2: +3.30 V (min = +2.86 V, max = +1.66 V) ALARM

And this could be +3.3V.

> in3: +2.99 V (min = +2.05 V, max = +3.36 V)
> in4: +2.59 V (min = +3.49 V, max = +2.14 V) ALARM
> in7: +2.94 V (min = +0.16 V, max = +0.42 V) ALARM

These ones are probably greater voltages (+5V, +12V...) scaled down. Or
in4 may be Vdimm.

> in8: +3.30 V (min = +0.38 V, max = +3.14 V) ALARM

I'd guess 3VSB (same as +3.3V but when your system is in standby mode.)

If you only have these two slow fans in the box, that looks OK.

May be OK too. You should set temp1's limits to something more
reasonable though.

Bogus, and this is expected as the W83687THF needs completely different
code for VID, which my initial patch didn't have. I've implemented
that now, a new patch is available here:

http://jdelvare.net2.nerim.net/sensors/hwmon-w83627hf-add-w83687thf-support.patch

Note that it only applies to Linus' git tree (or any recent mm tree),
not 2.6.15 - unless you fix the few rejects manually.

You're welcome. If you happen to test the patch linked above, please
report the result. Also, I'd like to work on a sample configuration
file for this chip. As the chip is quite rare, maybe we can simply
write a configuration file for your board. Can you please visit the
BIOS setup screens of your system and report all the hardware
monitoring items listed there, in order, with value? Then I'll provide
a configuration file for you to test.
