Hence, only option left is to use printk() directly. > Hello, When applying this series I am no longer able to start an AP on a DFS channel. (I don't know specifically which patch though) After the initial CAC period I get the following kernel message: [ 45.248441] ath12k_pci 0003:01:00.0: cannot install key for non-existent peer 3a:07:16:d8:00:08 And then hostapd goes in failed state: wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE ACS: Automatic channel selection started, this may take a bit wlan0: interface state COUNTRY_UPDATE->ACS wlan0: ACS-STARTED wlan0: ACS-COMPLETED freq=5620 channel=124 wlan0: interface state ACS->DFS wlan0: DFS-CAC-START freq=5620 chan=124 sec_chan=1, width=2, seg0=114, seg1=0, cac_time=5s wlan0: DFS-CAC-COMPLETED success=1 freq=5620 ht_enabled=0 chan_offset=0 chan_width=5 cf1=5570 cf2=0 radar_detected=0 wlan0: nl80211: kernel reports: key addition failed Interface initialization failed wlan0: interface state DFS->DISABLED wlan0: AP-DISABLED Maybe I missed something ? Is there another series this one depends upon that I should have applied before ? Thanks
