Had a tap0 configured through rc.conf at boot-time, and started a vkernel with -I tap0:bridge0. When I did this, I noticed that another tap0 was created (doing "ifconfig" showed 2 tap0 devices with different MAC addresses), so I did a "ifconfig tap0 destroy" and got a panic.
The kernel.X and vmcore.X are at leaf:~rumko/crash/tap/, sources used from approximately 13:00 CEST today.
