OK, BTW I have errors like - "Microcode SW error detected." upon monitor up - "iwlwifi 0000:02:00.0: FW error in SYNC CMD TXPATH_FLUSH" sometimes after the subsequent ieee80211_restart_hw - "WARNING: ... iwlwifi/mvm/binding.c:201 iwl_mvm_binding_remove_vif" when removing a monitor iface You must have seen those too. I will avoid this tree with iwlwifi then.
