Keep in mind regulatory hints for Intel or Atheros cards do nothing
other than help compliance further given that the cards already have
their own regulatory data, the user input / hint is only going to
reduce the card's channels further. That said the fact that you are
not seeing a regulatory domain being set is an issue provided you have
CRDA installed or use CONFIG_CFG80211_INTERNAL_REGDB. Keep in mind
that the latest version of wireless-regdb had a signature issue
reported by users and not sure if that is cleared yet, so that would
also prevent the wireless-regdb being read even if CRDA was present.
To rule that out try putting the db.txt into net/wireless/db.txt and
compile with CONFIG_CFG80211_INTERNAL_REGDB for now.

Then send the dmesg output, no need for all that fluffy intel debug
log as its not useful in this case.
