From 584d55be66ef151e6ef9ccb3dcbc0a2155559be1 Mon Sep 17 00:00:00 2001 From: Ben Copeland Date: Tue, 23 Sep 2025 21:26:56 +0200 Subject: [PATCH] hwmon: (asus-ec-sensors) increase timeout for locking ACPI mutex Some motherboards require more time to acquire the ACPI mutex, causing "Failed to acquire mutex" messages to appear in the kernel log. Increase the timeout from 500ms to 800ms to accommodate these cases.
