I am not reproducing this on a BE200 on the latest dev image on a WLAN Pi Go. I'm on a different kernel though.

Looks like we're using the same NIC.

@gcastle2007 did you switch from another application using the Interfaces to profiler? Perhaps kismet or had an streaming connection up?

[gcastle2007]

It is fresh loaded image 3.4.2 with completed apt update and apt upgrade.
Wi-Fi adapter Intel BE200.

Sorry... picture...

Can you run with 11be enabled again but with the --expert flag? That will increase the logging verbosity for the hostapd subprocess and might give us a clue.

I just flashed a dev image of Bullseye (v3.4.3 in the works) with the same kernel version, profiler version, ucode, adapter, etc. Did not see the same behavior right away. The generated hostapd config is identical.
