I noticed that I have to do ifdown wlan0 before I can change the mode with iwconfig. When I do it while the interface is up I get a error that the device is busy.

It is busy.

It seems to happen with ad-hoc, master and back from them to managed.
Is this a bug in the iwlwifi driver or in mac80211 ?

Neither, it is expected behaviour.
ok thx for this info.
 Blame it on Jean that wireless
extensions are ill-defined and don't mandate this.

Because of this NM can't create ad-hoc networks because it does it while the device is up.
Any ideas?

Fix NM?

Dan, something for you  ;)
does NM knows if the driver is a mac80211 one?
