That config is minimal, so I don't see anything offhand which would trigger
IPv6.
But there could be something else running on the system that triggers it.

Do you have *any* kernel modules which are installed on the system and not
built as part of the buildworld/buildkernel process?  For example, kernel
modules
installed via a port?

Lastly, since your crash is triggered by "sysctl -a" with VIMAGE and DDB
added to a GENERIC kernel config in 10.1,
can you see the last sysctl which is printed out before the panic occurs?
