From ce5ae93d1a216680460040c7c0465a6e3b629dec Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Sun, 15 Mar 2026 07:24:15 +0900 Subject: [PATCH 1/2] ata: libata-core: disable LPM on ADATA SU680 SSD 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.

However, in the case of an invalid command format, the sense data field incorrectly indicates byte 1 of the CDB. Fix this to indicate byte 2 of the command.
