        hf@Hochstuhl:/var/obj/netbsd-builds/8/amd64/sys/arch/amd64/compile/FIFI
Architecture: x86_64
Machine: amd64
>Description:

	The machine in question is supposed to bridge  ethernet
	segments with several VLANs.

	The etherip(4) driver was added to the kernel config (it is
	only in ALL, not in GENERIC), and etherip0 was configured for
	tunneling to a remote machine, then added to a bridge together
	with a local NIC (wm1).

	While booting to multi-user, the machine panics with 

panic: kernel diagnostic assertion "ifp->if_percpuq == NULL" failed: file "/public/netbsd-8/sys/net/if.c", line 1103

	The full boot log:

>How-To-Repeat:

	Set up a tunnel with etherip(4), bridge it to local NIC. I
	have not yet figured out whether setting up etherip triggers
	the panic, or adding the device to the bridge.

	
>Fix:
	Yes, please.
