Applying the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk for these SSDs resolves the issue, and they all work after this patch: /dev/nvme0n1 2J1120050420 ADATA SX6000LNP [...] /dev/nvme1n1 2J1120050540 ADATA SX6000LNP [...] Signed-off-by: Misha Nasledov Signed-off-by: Christoph Hellwig --- diff --git a/drivers/nvme/host/pci.c b/drivers/nvme/host/pci.c index bb970ca82517b..dd10cf78f2d3e 100644 --- a/drivers/nvme/host/pci.c +++ b/drivers/nvme/host/pci.c @@ -3029,6 +3029,8 @@ static const struct pci_device_id nvme_id_table[] = { .driver_data = NVME_QUIRK_LIGHTNVM, }, { PCI_DEVICE(0x1d1d, 0x2601), /* CNEX Granby */ .driver_data = NVME_QUIRK_LIGHTNVM, }, + { PCI_DEVICE(0x10ec, 0x5762), /* ADATA SX6000LNP */ + .driver_data = NVME_QUIRK_IGNORE_DEV_SUBNQN, }, { PCI_DEVICE_CLASS(PCI_CLASS_STORAGE_EXPRESS, 0xffffff) }, { PCI_DEVICE(PCI_VENDOR_ID_APPLE, 0x2001) }, { PCI_DEVICE(PCI_VENDOR_ID_APPLE, 0x2003) },
