   I am afraid that you may need to spell out each step for me :-(

   (kgdb) p *zone
No symbol "zone" in current context.
(kgdb) list *0xffffffff8067d3ee
0xffffffff8067d3ee is in uma_zalloc_arg (/usr/src/sys/vm/uma_core.c:1835).
1830                                ("uma_zalloc: Bucket pointer mangled."));
1831                            cache->uc_allocs++;
1832                            critical_exit();
1833    #ifdef INVARIANTS
1834                            ZONE_LOCK(zone);
1835                            uma_dbg_alloc(zone, NULL, item);
1836                            ZONE_UNLOCK(zone);
1837    #endif
1838                            if (zone->uz_ctor != NULL) {
1839                                    if (zone->uz_ctor(item,  
zone->uz_keg->uk_size,

   Is this that you were looking for?
