I forgot this yesterday: I accidentally compiled git master HEAD of that repo first. It worked fine, so something fixed this bug between v4.16.5 and 46dc111dfe47. If required I can try to bisect, but it will take a while, my CPU is almost 10 years old (takes 1+ hour to compile the kernel). I guess I could speed this up by using the pre-compiled debs to find a smaller range of commits first.
