From 25e424eb4ae1a662d9c3573218d06ac32f797fc5 Mon Sep 17 00:00:00 2001 From: Chris Sommers Date: Mon, 7 Sep 2026 11:27:23 -0700 Subject: [PATCH] Input: i8042 - add quirk for Acer Aspire Go 15 AG15-42P On the Acer Aspire Go 15 (AG15-42P), the internal keyboard drops out ~5 seconds after boot on both Linux and Linux-LTS kernels. Keystrokes on the built-in keyboard stop registering while the trackpad and external keyboards remain functional. Testing confirms that booting with the i8042.reset kernel parameter resolves the issue and keeps the internal keyboard responsive. Add SERIO_QUIRK_RESET_ALWAYS to i8042_dmi_quirk_table for the Acer Aspire AG15-42P to automatically apply this quirk on boot.
