# Check if modules are loaded lsmod | grep int340 If not auto-loaded:

Blacklist conflicting driver:

# List ACPI devices with INT33A0 ls /sys/bus/acpi/devices/INT33A0:00/ cat /sys/bus/acpi/devices/INT33A0:00/driver_override ls -l /sys/bus/acpi/devices/INT33A0:00/driver Step 2: Driver Loading Automatic Loading (Recommended) The driver should load automatically on supported hardware (Intel Bay Trail, Cherry Trail, Braswell, Apollo Lake, and newer).

Enable "Intel DPTF" or "Thermal Management" in BIOS/UEFI. Issue 3: Kernel Module Conflicts Some systems have conflicting thermal drivers ( acpi_thermal ). acpi int33a0 0 driver
