I can semi-reliably reproduce this panic message on a 9-CURRENT box, with sources from March 7. On this box, it happens every other time I start hastd. hastd creates the 12 GEOM providers used to create a ZFS pool. A simple "service hastd onestart" will generate the panic. Is there any extra info that needed to help track this down? --=20 Freddie Cash fjwcash@gmail.com
