oh okay, would it support linux libre 4.9 from jxself's website by the way?
as i've said - approximately five to eight times now - repeated both back in august, on the mailing list, and in the crowdfunding updates, repeatedly, and yet again, repeatedly, back only as far as ten days ago - nothing beyond 4.7rc4 works due to a mainline linux kernel bug that has not been fixed during a major reworking of various parts of the mainline sunxi.
As a matter of fact, there are dozens of other A20 based boards and they all work with the current mainline kernel. Many people are using them, so the test coverage is pretty decent.
I would not rule out some sort of defect in your hardware. For example, it has been recently discovered that some boards have wrong capacitors (10uF instead of 4.7uF) and this causes reliability problems:

And this was just a single example. There are tons of possible reasons why the hardware may not work correctly. And there will be no progress until somebody gets his hands dirty and finds the root cause.
