I am seeing the same problem on my HP laptop even with 5.5.y kernels.
I think this comes from mac80211.c where it is setting up the wait for a beacon:
mvmvif->csa_bcn_pending = true;
if (!fw_has_capa(&mvm->fw->ucode_capa,
IWL_UCODE_TLV_CAPA_CHANNEL_SWITCH_CMD)) {
u32 duration = 3 * vif->bss_conf.beacon_int;
/* Protect the session to make sure we hear the first
* beacon on the new channel.
*/
iwl_mvm_protect_session(mvm, vif, duration, duration,
vif->bss_conf.beacon_int / 2,
true);
}
To me it looks like a race somewhere in the session protection code. If there is already a TE running and it is cancelled etc.
Same problem here happening intermittently on a Dell Latitude 5401 with 5.3.0 kernel. Same problem exist in Ax200 intel Wifi card. Using Arch 5.6.13 latest Firmware git... How does a kernel will notify the iwd or networkmanager that "i just disconnected wifi", may be if i able to catch the event or notification, i cloud write my own program to restart the iwd.service, so it will reconnects to the 5gz wifi. thanks. The same problem exists with the Intel AX200 wifi card.
