I tested with ifconfig carp1 delete before destroy but the result is the same. tested on freebsd 6.2 pre-release i386 SMP and freebsd 6.2 release amd64 SMP - in both cases kernel panic. This seems very similar to this PR - http://www.freebsd.org/cgi/query-pr.cgi?pr=92776 I'm going to test on 6.2 stable from today, but I'm not very optimistic.
