Using sensors-detect
helped me finding the problem: The module it87
wasn't loaded. So I ran modprobe it87
which resulted in
ERROR: could not insert 'it87': Device or resource busy
Finally this link helped: I edited /etc/default/grub
and added acpi_enforce_resources=lax
to GRUB_CMDLINE_LINUX
:
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
Then executed update-grub
. Finally I had to add it87
to /etc/modules
, so that it gets loaded automatically on boot.
Reboot and now the output for sensors
contains an additional section (but yes, the old sections and temperatures didn't change).

temp1
and temp3
seem to report correct values. temp2
flaps between -10 and 60°C
