Hello. Thanks for the feedback. I'll try to get answers to your
questions soon and get back to you. The holidays are coming, and I'm not
sure how much time I'll have to dig into this in the next few days, but
I'll get to it, and we'll find the problem.

} The question is whether ath_hal_intrset does work or not. If it doesn't

} *not* set for you?
