Full /var/log/messages from iwm panic.

I tried to attach to an open of several open networks at "BornHack" yesterday and only managed to panic the iwm driver repeatedly.

I belive the AP's were Ubiquity, and I can probably get hold of the people who runs them if need be.

I have attached the full /var/log/messages as attachment, but here are what I guess is the top-level info:

I'm experiencing the same issue. Running the same release of FreeBSD as OP.

One difference in my case is that I get this error typically after resuming from sleep when connected to home network. Driver panics with iv_state = 2 rather than iv_state = 3 as in the original post.

According to the messages my wireless device is:
Intel(R) Dual Band Wireless AC 7265

Just wanted to update here. After upgrading to 12.1 the issue seems to have been resolved.
