--- Comment #2 from Eugene Grosbein <eugen at freebsd.org> ---
Please try attached patch. It should replace a panic with packed drop if an
interface being added to an aggregate is up and receives a packet in process of
inclusion to the aggregate.

Apply it with command:

cd /usr/src && patch < /path/to/patch

Then rebuild if_lagg.ko kernel module if you use it:

cd /usr/src/sys/modules/if_lagg
make obj depend && make all install

Or rebuild the kernel if your kernel configuration includes device lagg.
