Very well, but: If it can't access the CRDA and it is setting the world domain, why on earth is it blocking any subsequent requests to setting the regulatory domain from userspace when the CRDA *is* accessible ? I mean, i could see the need to do something *temporary* at boot when accessing the CRDA fails and to take the most safe default for the time being .. The BUG is that it is NOT temporary, but blocking until next reboot because the first request wasn't completely processed. My hostapd will try to set the domain when it starts and at that point the CRDA is accessible, so it would set it from the temporary domain to the one specified, as long as it isn't blocking. > Regards, > Arend -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
