From 717c6f4570a6715bc19e8975cad1a90a1e46f4a5 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 10 May 2022 08:11:36 -0500 Subject: [PATCH] ACPI: PM: Block ASUS B1400CEAE from suspend to idle by default [ Upstream commit d52848620de00cde4a3a5df908e231b8c8868250 ] ASUS B1400CEAE fails to resume from suspend to idle by default. This was bisected back to commit df4f9bc4fb9c ("nvme-pci: add support for ACPI StorageD3Enable property") but this is a red herring to the problem. Before this commit the system wasn't getting into deepest sleep state. Presumably this commit is allowing entry into deepest sleep state as advertised by firmware, but there are some other problems related to the wakeup. As it is confirmed the system works properly with S3, set the default for this system to S3.
