Could you test this instead? https://p.sipsolutions.net/235c352b8ae5db88.txt I don't have that much sympathy for a staging driver that's clearly doing things differently than it was intended (the documentation states that the function should be called only before wiphy_register(), not during ndo_open). :-) But OTOH, that fix to the driver is simple and looks correct to me since it only ever has a static regdomain, and the notifier does the work of applying it to the channels as well. > One thing which I forgot to mention earlier, it is not just lockdep complaining > this appears to be a real deadlock, the wifi no longer functions, where > as it does function with the patch drops. Right. johannes
