Comment 5 for bug 1806108

This is the first time I think we've been asked to test something on rpi3 arm64. The core 16 images we normally test the kernel snaps on are 4.4 based. I did try this on a core18 image and was unable to reproduce the problem, but it's not arm64. So this could be arm64 related, or as Paolo seems to be finding, could be related to something else like flash-kernel?
