Subject: Re: Stack dump, Pi 4B, Debian Bookworm (not RpiOS)

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

[  278.673598] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown

In spite of that, WiFi and Ethernet seem to be working.

best,
