I was learning some Pentoo (Gentoo) linux security distribution stuff this evening, just some scrap notes that might help someone else out with any airmon-ng issues.
If you are trying to put a wireless nic into monitor mode, make sure you do not have any wifi profiles saved to connect over wireless to an AP, if you do you may see the following (partial):
sudo airmon-ng start wlan# (where # is the wireless interface you are bringing up)
airmon-ng "is soft blocked ... please run "rfkill unblock #"
I figured this out by remembering I had connected to my wifi to update the distro, I manually deleted the wireless profile and wholla, it's working again w/airmon-ng and kismet.
