Wysocki" , linux-acpi@vger.kernel.org, devel@acpica.org Hi, after upgrading to 4.9-rc1 I get the following errors occasionally during boot and suspend-to-ram on an APL system: [   59.513434] ACPI Error: [TMP_] Namespace lookup failure, AE_ALREADY_EXISTS (20160831/dswload2-330) [   59.513446] ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20160831/psobject-227) [   59.513469] ACPI Error: Method parse/execution failed [\_SB.PCI0.SCPG] (Node ffff8802770b7bb8), AE_ALREADY_EXISTS (20160831/psparse-543) [   59.515415] ACPI Error: Method parse/execution failed [\_SB.PCI0.SDHA._PS3] (Node ffff8802770b7dc0), AE_ALREADY_EXISTS (20160831/psparse-543) [   59.517118] ACPI: Marking method _PS3 as Serialized because of AE_ALREADY_EXISTS error Other than these error messages, booting and suspend/resume seems to work ok.
