 Thanks John for your response.
 
 Here is the output provided what you had explained to do:
 
 
 0xffffffff80865023 is in devstat_remove_entry
 (/usr/src/sys/kern/subr_devstat.c:193).
 188
 189             /* Remove this entry from the devstat queue */
 190             atomic_add_acq_int(&ds->sequence1, 1);
 191             if (ds->id == NULL) {
 192                     devstat_num_devs--;
 193                     STAILQ_REMOVE(devstat_head, ds, devstat, dev_links);
 194             }
 195             devstat_free(ds);
 196             devstat_generation++;
 197             mtx_unlock(&devstat_mutex);
