trouble with hostapd

[e9hack]

I've trouble with 5GHz since the last changes related to hostapd. After boot or after a sequence 'wifi down; sleep 30; wifi' the 2GHz starts only. The 5GHz doesn't start. It looks like, that ACS isn't started. If I modify a value in the config related to 5GHz and execute 'wifi reload', sometimes 5GHz starts.

If I remove ACS and set a fixed channel, 5GHz starts only, if the channel doesn't need DFS because DFS is never finished successful.

If I revert mac80211.sh and hostapd.sh back to the older versions, ACS and fixed channel with DFS does work again.
