Björn,

Back on 7/13 at 09:33 UTC, I sent you an email also showing a panic.
It may be similar as it also involves lkpi_sta_auth_to_scan() and then
lkpi_lsta_remove().

In my case, it was triggered by doing:
	ifconfig wlan0 down up
on an already-associated interface with an address from DHCP.

This is on the 8265.

Here's the backtrace again...
