    Hmm... I don't see any timeout in the log you posted. Ah, okay, the
    interesting part is in the full log, the ACPI GTF sequence itself is
    finishing fine but the next NCQ READ command is timing out. The BIOS
    is enabling non-zero buffer offsets and DMA setup FIS auto-activate.
    It's likely that the controller isn't being configured correctly
    leading to mismatch between the behavior expected by the controller
    and the actual drive behavior. Hmm.... I'll look further into it
    tomorrow. For the record, can you please attach the full log, lspci
    -nn output and dmidecode output here?
