I spend a bit of quality time with this bug today and it seems there is (also?) 
a kernel dimension to it. I ran the following:

which essentially moves the image to a 2 month older 4.14 kernel. With that I 
could not reproduce the error for three subsequent runs of 2 repeats.

However when I disabled this code and use the current "18/edge" pc-
kernel (or stable, it's the same revision) then I can trigger the bug
right away.
