We have then bisected the issue together with them within the mainline kernel sources to the following commit that changes the default power policy: 7627a0edef54 ("ata: ahci: Drop low power policy board type") The user reports that adding "ahci.mobile_lpm_policy=3D1" as a kernel parameter fixes the issue for them. Additionally fellow forum user @loqs came up with a quirk patch, that sadly was reported to not work: diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index c085dd8..ef01ccd 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -4118,6 +4118,9 @@ static const struct ata_dev_quirks_entry __ata_dev_qu= irks[] =3D { { "SAMSUNG MZ7TD256HAFV-000L9", NULL, ATA_QUIRK_NOLPM }, { "SAMSUNG MZ7TE512HMHP-000L1", "EXT06L0Q", ATA_QUIRK_NOLPM }, =20 + /* Hitachi-LG Data Storage models with LPM issues */ + { "HL-DT-ST BD-RE BU40N", NULL, ATA_QUIRK_NOLPM }, + /* devices that don't properly handle queued TRIM commands */ { "Micron_M500IT_*", "MU01", ATA_QUIRK_NO_NCQ_TRIM | ATA_QUIRK_ZERO_AFTER_TRIM }, So if anyone has feedback on why the patch does not work or any alternative ideas for a solution that would be highly appreciated!
