ipset *triggered* the problem. The whole stack dump would tell more.
OK, find the stack traces in the bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1272645

Kernel 4.1.10 triggered also a kernel dump when playing with ipset commands
and IPv6, details in the bug report ....

Kernel 4.2 seems to me not well tested in the netfilter parts at all
(Bug with already known bugfix
https://lists.debian.org/debian-kernel/2015/10/msg00034.html was
triggered on 2 of 3 of my machines, the new bug on 1 of 1 tested machine).
There's a reason why Greg maintains stable and LTS kernels :-)
Stable kernels don't crash but definiton. :-)

At least triggered 2 kernel panics in 5min, even with 4.1.10 and ipset
commands ...
Does this happen also with Linus's tree? I suggest you ask the
networking developers about this on netdev@xxxxxxxxxxxxxxx, there's
nothing that I can do on my own about this, sorry.

Already CCed netdev and netfilter-devel mailinglist. Need patches for the switch driver of the banana Pi to get networking up but that patch is stable. Maybe also some patches from the Fedora SRPMS are needed. But I'm pretty sure that this also happens with plain vanilla kernel.

Ciao,
Gerhard
