I'd start with freebsd-fs@ and file a proper PR if there's
still no response after a few weeks or so.

If you haven't already, you might want to skim through:
http://www.freebsd.org/cgi/query-pr-summary.cgi?&text=zfs
first, to see if your problem is already known.

Additional information about the panic itself will probably do at
the beginning, you can always provide more later if someone asks for
it.

For details see:
