Without backtrace is really hard to guess what's the cause of
panic. So please send backtrace to us.

Would you be more elaborate on this issue? Does it mean you have
to manually up/down game with ifconfig(8) after boot?

7.1-RELEASE would be the first official release that will ship
age(4). So I don't think it was well tested under various
workloads. But if you can provide more information for the issue
I think it could be enhanced in near future.

Remember, all hardwares supported by age(4) are for consumer
motherboards. Even if L1 has much better performance/design than
that of its successor, L1E, it's still not for server market.
The same is true for em(4). Since there are too many variants you
may have to choose the best hardware model that is suited for your
workload.
