If anyone has any objections, please let me know. ------------------ From: "Mario Limonciello (AMD)" [ Upstream commit 4d3a13afa8b64dc49293b3eab3e7beac11072c12 ] Titas reports that the accelerometer sensor on their laptop only works after a warm boot or unloading/reloading the amd-sfh kernel module. Presumably the sensor is in a bad state on cold boot and failing to start, so explicitly stop it before starting.
