igb0: core crash (if_io_tqg_0) VLAN

[O. Hartmann]

Running CURRENT (FreeBSD 12.0-CURRENT #0 r320050: Sat Jun 17 11:03:50 CEST 2017 amd64) on
PCengines APU 2C4: CPU: AMD GX-412TC SOC with recent Sea BIOS.
The APU is configured as a small router. The tun0 device is spawned from igb0 and bound
to ppp (providing the conenction to my ISP).

igb1 is the internal NIC and it is a Intel i210, identified as igb1. The NIC is
configured to bear a also a VLAN called igb1.2 providing a dedicated VoIP network
framework on which I'm working for some tests. So far, that setup worked wit a
12-CURRENT roughly two weeks old - I don't have the revison at hand.

Firewall is IPFW.

The very moment I plug in the uplink to the switch, the APU goes down with an coredump:
