Hi Mark! Sure the patch is this one: https://github.com/balena-os/balena-beaglebone/blob/master/layers/meta-balena-beaglebone/recipes-kernel/linux/linux-beagleboard-4.14/0001-card-power-cycle.patch I think that only the msleep(10) should be necessary. Nevertheless I added both lines stated in the patch. I repeat myself, I don't have the knowledge to explain why it works. This might not be a proper solution, but for me it worked flawlessly. It started without troubles all the times. I think that this might not be the optimal solution, but it can lead the path to it. If more information, testing or logs are needed. Keep writing to me and I will do them.
