piix4_smbus 0000:00:07.3: SMBUs Host Controller not enabled!What does it means ?
This error occurs when the SMBus (System Management Bus) host controller, managed by the piix4_smbus driver, is not enabled in the system's BIOS/UEFI firmware.
SMBus is used for system monitoring and power management, commonly to access temperature sensors, voltage monitors, fan speed controllers, or battery status in embedded controllers.
It operates over the I2C (Inter-Integrated Circuit) protocol.
This means your running inside a Virtual Machine that did not have this feature.
If Artica is running under a bare metal box
- Enter the BIOS/UEFI Setup during boot (e.g., DEL or F2 key).
- Locate settings under Advanced > Chipset Configuration or South Bridge Configuration.
- Ensure the
SMBus Controlleris enabled.
