So at least a work around for now. I will add the echo command to
the
/etc/rc.d/rc.local script.
The readings still seems strange, so use such workarounds only in case
you are really sure that the temp is OK. FYI it is also possible to set
the sensor type in /etc/sensors.d (by copying and modifying the
appropriate it87 config parts from the /etc/sensors3.conf).
Blacklisting the it87 module should also prevent the machine from halt.
Please file a bug about it.
