I have the same problem, and for me it seems unrelated to kernel revisions. I have a whole bunch of Orange Pi Zeros, all running the same kernel and all with the same updated packages. However, the ones that run from old SD cards and have been updated from earlier releases, they reboot fine, while those that running from relatively recently flashed SD cards struggle and halt instead of reboot. Since this is super annoying, I wish to find out what's causing this, so I will do some diffing between the systems to see if I can find the culprit.
