So in my case the stop request is cancelled, probably because the state has changed from dead to tentative quickly enough. So this looks like a race indeed. I also tested v227 and it shows exactly the same behaviour. So this issue has been lurking for a while (see attached journal) it seems. My guess is that it goes way back until [1] or even [2]. So the best guess is that the timing in v228 changed a little (some code paths became faster). This would confirm Frank's findings that enabling verbose output (which slows down boot a bit) made it less likely to hit. Martin has been working/debugging the tentative stuff in the past, so maybe he has some insights here. We should probably also involve upstream at some point.
