The calculator key (Fn + numpad =) emits a press event but never a release, leaving KEY_CALC permanently held down. Desktop environments then repeatedly spawn the calculator. Before: MSC_SCAN a1 / KEY_CALC value 1 (no release for the remaining 24s of the capture) After: MSC_SCAN a1 / KEY_CALC value 1 MSC_SCAN a1 / KEY_CALC value 0 (14us later) Scancode 0xd7 (Fn+F4) is an atkbd echo of the mic mute key that ideapad-laptop already reports as KEY_MICMUTE with a proper press/release pair. Mapping it to unknown silences the repeated "Unknown key pressed" kernel messages without affecting the working key. Tested on Fedora 44, kernel 7.1.10, BIOS P5CN31WW.
