Error -16 is EBUSY, which causes the driver load to fail due to the "Unable to reserve mem region" message.
This means that the sata_nv driver needed to use PCI BAR 6, but was unable to for some reason. Given that sata_nv uses devres like other libata drivers, IMO the likely cause is outside the ATA subsystem (PCI? ACPI?).
One workaround to try is setting sata_nv module option 'adma' to zero (0), in the hopes that it ignores that final region and work anyway.
