For what it's worth, Bernd contacted me because it looks like this was the
cause of https://lore.kernel.org/lkml/20180605085450.GA3506@scapa.corsac.net/

I wanted to try Bernd patch, unfortunately I wasn't able to reproduce the
freezes on more recent kernels, so right now I can't add a Tested-By, but I'd
be happy to be kept on CC.
