From 9ba75ccad85708c5a484637dccc1fc59295b0a83 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 11 Jun 2025 15:33:40 -0500 Subject: [PATCH] platform/x86/amd/pmc: Add PCSpecialist Lafite Pro V 14M to 8042 quirks list MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Every other s2idle cycle fails to reach hardware sleep when keyboard wakeup is enabled. This appears to be an EC bug, but the vendor refuses to fix it. It was confirmed that turning off i8042 wakeup avoids ths issue (albeit keyboard wakeup is disabled). Take the lesser of two evils and add it to the i8042 quirk list.
