I'm not running and dev branch modules, so this may be known already but not trickled up. Nov 21 08:03:26 thinkpad-e545 logger: ACPI group ibm / action hotkey is not defined Nov 21 08:03:58 thinkpad-e545 kernel: [ 1196.083017] thinkpad_acpi: unhandled HKEY event 0x6060 Nov 21 08:03:58 thinkpad-e545 kernel: [ 1196.083021] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx Conditions: Thinkpad E545 Latest Slackware standard kernel (updated yesterday): vmlinuz-huge-3.14.18 Syslog IDs the module and computer as: thinkpad_acpi: ThinkPad ACPI Extras v0.24 thinkpad_acpi: ThinkPad BIOS HRET24WW (1.12), EC unknown thinkpad_acpi: Lenovo ThinkPad Edge E545, model 20B2CTO1WW thinkpad_acpi: detected a 8-level brightness capable ThinkPad thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver 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... BIOS configured to use legacy function keys, so the <Fn> key is used for triggering ACPI buttons. (This is a change from the as-shipped default.) Press and hold the <Fn> key for several seconds and the event above appears in /var/log/messages. As an FYI, the syslog message implies that the brightnessup / brightnessdown events will not trigger the system acpi_handler script, but that is not true. I just added them to the script to keep them out of my logs.
