+- There's module/chip/sensor errors in the output or `journalctl`:
+    - If you know which chip and sensor (e.g. if it shows it during output), try adding `chip "<chip>"\n    ignore <sensor>` in `/etc/sensors3.conf`. Re-run `sensors`. (See [Kernel ACPI Error SMBus/IPMI/GenericSerialBus (ServerAdminBlog)](https://www.serveradminblog.com/2015/05/kernel-acpi-error-smbusipmigenericserialbus/) for an example on certain HP servers.)
+    - If you know which module it is, try to unload it. Re-run `sensors`. If it worked, then remove it from `/etc/modules` to make it permanent.
