core crash summary

I have yet another 10.2-RELEASE + iwn driver panic.

cloned_interfaces="bridge0 tap0 tap1"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"
ifconfig_em0="DHCP"
autobridge_interfaces="bridge0"
autobridge_bridge0="tap* em0 wlan0"

If the autobridge line is commented out, the system does not panic on boot.
