For anybody following this thread and wondering...

Developers confirmed that nullfs was the neccesary ingredient required
to induce this panic.  A fix was produced, tested, and committed to head
on 2013-10-10 as r256211.  I applied that patch to releng/9.2 a week ago
and have had releng/9.2 + r256211 patch running on two servers since
then.  All looks good.

That patch was MFC'd to stable/9 this morning as r256590.

Thank you to those who diagnosed this panic and produced the patch.
