            Bug ID: 269824
           Summary: iwlwifi sporadic loss of connectivity, then kernel
                    panic on service netif restart
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: wireless
          Assignee: wireless@FreeBSD.org
          Reporter: maxim.usatov@bcsatellite.net

Experiencing sporadic loss of wireless connectivity, ifconfig just shows "" in
ssid. Doing service netif restart results in kernel panic.
