So the bad part of bff1cef5f23afbe49f5ebd766980dc612f5e9d0a is found. As additional information, my previous kernel has CONFIG_PHY_TEGRA_XUSB=m (since firmware is on rootfs which is on sata) but with this sata fail the same, having CONFIG_PHY_TEGRA_XUSB=y (and so xusb firmware in kernel) seems "necessary" for having SATA working.
