Which kernel tree are you using ? Did you not only update the uImage but also the dtb? I'm not seeing
any ahci related messages at all in the new dmesg output, so it seems that either your dtb does not have
an ahci node (or not with the proper compatible= string), or sunxi-ahci is not build into your kernel.
