Subject: [PATCH] ata: libata-core: disable LPM on ADATA SU680 SSD
Date: Sun, 15 Mar 2026 07:24:15 +0900	[thread overview]
Message-ID: <20260314222415.51176-1-dlemoal@kernel.org> (raw)

ADATA SU680 SSDs suffer from NCQ read and write commands timeouts or bus
errors when link power management (LPM) is enabled. Flag these devices
with the ATA_QUIRK_NOLPM quirk to prevent the use of LPM and avoid these
command failures.
