@IgorDo what I do: ignore idiots, "ready, aim, fire" as opposed to "fire, aim, ready" once the target is properly identified as an idiot.
Your frustration and all the time / energy you waste is due the ignoring the reality of humanity: 5% criminals, 90% followers (idiots), 5% leaders.
Which is best: shutting down the forum because YOU are annoyed with reality, or, ignoring time wasters? Be aware the the corporations / individuals who are able / choose to pay 10K for support do so because of Armbian excellence which is a product of understanding / dealing with / solving issues from a large user (test) base.
FACT: you say I am close to solving my stated issue (and, I am, it appears to be an upstream issue, incomplete headers), implying that you see the solution and yet, waste all your time / energy complaining about people who ask questions, assuming ALL (except you) are non-contributors. Would have been better (less effort) to just answer the question so nobody (responsible enough to research) annoys you again.
My point is NOT that I am annoyed / insulted by your unfounded opinion regarding me and those who ask questions. My point is to convince you that your frustration is a product of how YOU choose to deal with matters. Sometimes, smart people miss the simplest things, as you have.
because this is a "help" forum and, every answered question eliminates it being asked again and contributes to excellence. Just today, my WiFI patch helped two people who didn't have to annoy you by asking.
Please keep your "bad day" to yourself and don't call a professional evaluation and thank you for the excellence of Armbian and developers "BS".
