I've bisected it and landed on: cfc1a472a8d89c0d0bbb3600501eeeebc5ec8039 is the first bad commit commit cfc1a472a8d89c0d0bbb3600501eeeebc5ec8039 Author: Rafael J. Wysocki Date: Sat Oct 9 16:22:09 2021 +0200 ACPI: scan: Release PM resources blocked by unused objects [ Upstream commit c10383e8ddf4810b9a5c1595404c2724d925a0a6 ] On some systems the ACPI namespace contains device objects that are not used in certain configurations of the system. If they start off in the D0 power state configuration, they will stay in it until the system reboots, because of the lack of any mechanism possibly causing their configuration to change. If that happens, they may prevent some power resources from being turned off or generally they may prevent the platform from getting into the deepest low-power states thus causing some energy to be wasted. Address this issue by changing the configuration of unused ACPI device objects to the D3cold power state one after carrying out the ACPI-based enumeration of devices.
