The chip can't support the channels, so it warns:
invalid arguments, band=1, bw=2, path=1, rate=60, ch=130
Does it still warn if you connect to channel 8 on 2.4GHz band?
I think it should not.

What does the channels you tested? How about 5GHz channel 36 with
bandwidth 80MHz?

We are considering to disable the channels [1], because these channels
doesn't get certificated and tested.
A people proposed a patch [2], which you can pick it to test locally,
but I don't think it will be the solution.

You can consider them as independent modules except to antenna sharing.
