I should have mentioned that I'm also running Tailscale and Docker on this host so there's a lot of "networking" going on. Following a reboot, I see what I think is the same stack dump. In addition there are a lot of messages on the console like [ 242.666852] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x5, action 0x1 [ 251.665022] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x5, action 0x1 [ 260.716149] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x5, action 0x1 [ 269.670253] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x5, action 0x1 [ 278.673598] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x5, action 0x1 In spite of that, WiFi and Ethernet seem to be working. best, On Tue, Apr 22, 2025 at 11:52 AM Hank Barta <hbarta@xxxxxxxxx> wrote: > > Good morning, I encountered the following while attempting to connect > to a WiFi AP using iwd.
