4 years ago Do you have any LOR info before that?
So I know there are a few LORs that need squishing still. :-)
A bunch of firmware messages do come by when we delete a node; those notifications shouldn't hurt. Ideally we'd go through the machinery of issuing delba and ensure crypto key deletion before we issue the peer teardown, but net80211 isn't quite ready for that.

Hit a "deadklock".
I assume it's more likely that the firmware went kaboom after this
