 Could you please give the following patch a try?
 http://people.freebsd.org/~marius/mpt_MPI_EVENT_QUEUE_FULL_non_member_MPI_EVENT_SAS_DEVICE_STATUS_CHANGE.diff
 It should make mpt(4) report the SAS device discovery and departure events
 to cam(4) but I don't know whether higher levels like geom_mirror(4) or
 zfs(4) will handle these properly.
