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.

It appears too many like like below in dmesg after applying the patch in a
virtual machine.
