I've trouble with the following commit:

commit	3aa96efa24c13c6e0aafa5ad826f3f95a3bd74f9
mac80211: Update to version 5.15.33-1

After this commit the 5G wifi interface doesn't start properly. The interfaces are visible with ifconfig, but it isn't visible on air. To get 5G working, I must restart hostapd. I'm doing this with the following command 'wifi down; sleep 5; killall -9 hostapd; sleep 5; wifi &'.

Any idea, what is wrong in mac80211 5.15.33-1?
