Unfortunately, no such luck when built as modules with the debian config with mainline linux 541d8f4d59d79f5d37c8c726f723d42ff307db57: [ 5.195698] ahci 4a140000.sata: couldn't get PHY in node sata: -517 [ 5.207222] ahci 4a140000.sata: SSS flag set, parallel bus scan disabled [ 5.207244] ahci 4a140000.sata: AHCI 0001.0300 32 slots 1 ports 3 Gbps 0x1 impl platform mode [ 5.207251] ahci 4a140000.sata: flags: 64bit ncq sntf stag pm led clo only pmp pio slum part ccc apst [ 5.229994] ata1: SATA max UDMA/133 mmio [mem 0x4a140000-0x4a1410ff] port 0x100 irq 321 [ 15.231005] ata1: softreset failed (1st FIS failed) [ 25.234595] ata1: softreset failed (1st FIS failed) [ 60.238725] ata1: softreset failed (1st FIS failed) [ 60.243852] ata1: limiting SATA link speed to 1.5 Gbps [ 65.414439] ata1: softreset failed (device not ready) [ 65.419747] ata1: reset failed, giving up Will test if it still works as a built-in later, and linux-next for good measure. live well, vagrant
