Actually, I already rolled back my kernel to August 1st:

# svn info .
Path: .
Working Copy Root Path: /usr/src
URL: http://svn0.us-west.freebsd.org/base/head/sys
Repository Root: http://svn0.us-west.freebsd.org/base
Repository UUID: ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f
Revision: 253847
Node Kind: directory
Schedule: normal
Last Changed Author: ian
Last Changed Rev: 253847
Last Changed Date: 2013-07-31 21:14:00 +0200 (Wed, 31 Jul 2013)


And the problem seems to have gone away.  I could perform a full zfs
send/receive whereas it would trigger a panic 100% of the time with a
recent kernel.
