Hi! I just found out that thinkpad_acpi.ko is not automatically loaded on new ThinkPad T480s. Is there any reason for it? Manually calling modprobe thinkpad_acpi is working fine, but I would expect that it should be loaded automatically. Here is dmesg output after loading it manually: thinkpad_acpi: ThinkPad ACPI Extras v0.25 thinkpad_acpi: http://ibm-acpi.sf.net/ thinkpad_acpi: ThinkPad BIOS N22ET34W (1.11 ), EC unknown thinkpad_acpi: Lenovo ThinkPad T480s, model 20L7S03000 thinkpad_acpi: radio switch found; radios are enabled thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver thinkpad_acpi: Disabling thinkpad-acpi brightness events by default... thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked thinkpad_acpi: Standard ACPI backlight interface available, not loading native one -- Pali Rohár pali.rohar@xxxxxxxxx
