Ever since then, I had on-and-off problems where one or two of the test boots would fail. Usually a re-run would be successful. I originally blamed qemu and switched between versions, but that didn't help. This is the first release and branch where 8-10 of the 14 boot tests failed persistently when building the image with gcc 8.2.0. I finally had the idea to look at the compiler and, yes, switching back to an older version helped. I have no idea if gcc or qemu or the code itself is to blame. I am not sure if anyone would be interested enough to fix the underlying problem. I just wanted to mention it in case someone does care. If so, I'll be happy to help tracking it down further.
