The second card’s driver (also ath9k) calls regulatory_hint to provide US as a driver hint. ignore_request sees that the last request came from a driver (instead of the core) and since the regulatory domain is changing from 00 to US, decides that intersection must be performed. This interpretation however is incorrect, as a driver hint shall always be respected if the current regulatory domain is 00. We do end up with an intersection but there is another reason and that is the bug. I will try to track it down. Luis
