Comment 2 for bug 1846397

This seems like one of those bugs that one would never actually explicitly testing, because it doesn't make sense to treat as a separate test-case (i.e. testing with and without serial connected). Sadly there's not much one could have done automated-testing wise - we just need to use this as a lesson and dedicate one device with serial disconnected to make sure this test case is handled. From what Chris mentioned, this is now done, so we should be covered for the future!

For now I have asked Ondrej if he could take a look, since this might be something that got introduced with his latest dragonboard gadget update.

Ondrej: could you take a look? I'd like to know if this issue can be fixed easily - otherwise, per Chris Wayne's proposition, we'd probably want to revert the dragonboard images to the previous stable version. Since an older working image is better than a newer one that doesn't boot (for some cases).
