[AMD Official Use Only] Adding few more folks -----Original Message----- From: Hans de Goede <redacted> Sent: Sunday, August 1, 2021 3:17 PM To: Stephen MacNeil <redacted>; Limonciello, Mario <Mario.Limonciello@amd.com>; Rafael J . Wysocki <redacted> Cc: Linux PM <redacted>; linux-acpi <redacted> Subject: AMD laptops defaulting to S3 instead of S0ix (was amd_sfh) Hi Rafael, Mario, Stephen is having an issue with a recent AMD laptop (a Lenovo Ideapad model) where Linux defaults to using S3/deep suspend instead of S0ix/s2idle. This is causing the sensors provided by the AMD Sensor Fusion Hub to stop working after a suspend/resume. Adding mem_sleep_default=s2idle to the kernel commandline fixes this. Do you have any idea what might be causing this ? Regards, Hans On 7/31/21 2:31 PM, Stephen MacNeil wrote:

Thanks Stephen MacNeil,On our hardware we do not see any amd_sfh issue with 5.14.0-rc2 kernel. Could you please check with Lenovo, as we are not observing amd_sfh issue on our reference platforms too.
