When I said that I found the issue, I meant that you are using a NIC which is not supposed to work on 5GHz on these channels and this leads to the issues. The fact that it doesn't work for you with -8.ucode proves that I am correct. I sent a patch that will disable 5GHz band for you from the driver level so that you won't suffer from firmware asserts. You told me you could work on 5GHz with this NIC - good for you. Conclude whatever you want from this, this is none of my business - but for sure, the "issues" you are seeing are related to the fact that your NIC isn't supposed to be working on 5GHz, and hence, there is no bug to be fixed.
