Guys.
Its looking like a component issue. We're still testing here to get to the bottom of it. In the meantime, can you all please stop running your boards. I know this sucks but it will make things better in the long run. Whatever is going on here is fixable, but will be quicker and easier to fix if the boards are preserved as they are now rather than risking damage by running them while things aren't working as they should.
More soon.
