There's a project management lesson here. Raspberry Pi 4 was planned for 2020, but the Broadcom SOC went final much sooner than expected, so they shipped the Pi 4 this year. This sounds like a great thing, but the earlier release meant that the board as a whole spent less time being used internally before release, and they didn't have the time to shake out bugs like this. The lesson: when you move to a faster release cadence, you need to be more rigorous about QA because you have less time to find problems before release.
