Odds are that superiotool is wrong and your chip is actually a
WPCD377I. Please try the latest version of sensors-detect:
http://dl.lm-sensors.org/lm-sensors/files/sensors-detect

You can remove "lm85" and "i2c-i801" from this list.

This is the WPCD377I, which doesn't include sensors, thus all zeroes.

The alarms look wrong, unless the temperature were much higher at some
point before, and you did not run "sensors" since then. Do the alarm
flags wear off if you run sensors again after a few seconds?

> Are there any updates on this issue?

The "WPCD377I detected as LM96000" issue is tracked in:
http://www.lm-sensors.org/ticket/2182
and solved in sensors-detect since lm-sensors 3.1.1. The lm85 driver
still needs to be taught to ignore the WPCD377I.

Please see:
