But according to the "Modules linked", probably ghash is already loaded and perhaps tested.

But I got the same with plain next (like yesterday 5.6.0-rc2-next-20200219 and tomorow 5.6.0-rc2-next-20200220) and master got the same issue. But for reproductability on different hardware, I agree it is difficult. For the moment, I got it only on Allwinner H5, A64, H6 SoCs and imx8q.
