W83781D false alarms and temp readings *very* high (Examined/Solved - lm_sensors 2.6.4 Linux 2.4.18)

[contact]

W83781D is found by sensors-detect (and by us, looking on the main board).

Modules load fine.

Readings were fine with lm-sensors 2.5.5 on Linux 2.2.16.

Now (lm_sensors 2.6.4 on Linux 2.4.18) we get the following readings (after

reboot, without sensors -s):

The alarms are always there, each time we read the values.

The same (and more) errors occur with sensors 2.6.4 and the old modules (2.5.5)

on Linux 2.2.16, so we think the error must be somewhere in sensors.

Output of sensors 2.6.4 with the old modules (2.5.5) before sensors -s:

BIOS sais System Temp was 35, CPU Temp was 42. Voltage readings seem to be

correct.

It's also the same with a monolithic Linux 2.4.19 kernel patched by lm_sensors

2.6.4.

The board is a CA61 (www.dfi.com) with VIA 693A/596B chipset. --- more recent releases fixed errors in the library and

sensors.conf with negative voltage limits.

(for example in6_max should be -5 * 0.90 and min should be -5 * 1.1)

Fix the errors in your sensors.conf or copy over

new from etc/sensors.conf.eg and then new modules should

work fine.

Make sure you did 'make install' which installs the new libsensors as well.
