Using a very recent 4.10-STABLE GENERIC kernel with ipfilter, I was
getting these panics frequently.

When I compile a kernel (using make {build,install,}kernel in
/usr/src) I always compile all klds, so I don't believe I have
anything out of sync.

After I compiled a kernel identical to GENERIC except with DDB, call
path was

generic_bcopy
fr_check
ip6_input
ip6intr
swi_net_next

Disabling ipfilter has made the panics go away, as of several days
ago.

Any thoughts?
