This is on an Rpi B3+ runint aarch64. I have noticed that, periodically I
get disconnected and it doe snot reconnect. I am using connman to manage
the iwd connection. This is the first time I have seen the crash in the
log. It has been crashing and not recovering.
It gets a Deauth event (I've seen this quite a bit) and usually, it will
not reconnect until I reboot it and my router. How can I best diagnose this?
It is iwd 1.7 and connman 1.38. potentially useful excerpts from my journal:

Hmm, this implies the firmware tried to roam. Does your network have multiple
APs in the same SSID?
Can you run iwmon and get a trace of this happening? See
https://iwd.wiki.kernel.org/debugging for details.

Hmm, I suspect we fixed this particular crash in iwd 1.8. Can you try that?

Denis,
I just loaded iwd 1.8. Will debug if it starts happening again.
Thanks,
Keith
