Hi,
This mean u probably do not have crda installed, or it is not properly
configured. These are debug prints so the simplest would be to disable
CONFIG_CFG80211_REG_DEBUG .. unless you are debugging wireless regulatory flows.
Regardless, I'll try to come up with a better solution to handle such cases.
Thanks,
Ilan.
