Looks like a bug in the ciss driver.

                /* if never got a chance to be done above... */
                if (ccb->ccb_state != CISS_CCB_FREE) {
                        KASSERT(error);
                        ccb->ccb_err.cmd_stat = CISS_ERR_TMO;
                        error = ciss_done(ccb);
                }


Could you try to change that KASSERT(error); into a KASSERTMSG() and
print ccb->ccb_state? When savecore runs, it should log the full panic
message (in case you can not capture it at crash time).
