Hmm.. it appears to be in..
0xffffffff8048e2e7 is in sysctl_handle_int 
(../../../kern/kern_sysctl.c:816).
811              */
812             if (arg1)
813                     tmpout = *(int *)arg1;
814             else
815                     tmpout = arg2;
816             error = SYSCTL_OUT(req, &tmpout, sizeof(int));
817
818             if (error || !req->newptr)
819                     return (error);


So its trying to copy out and faulting.. not sure what..

Let me know if there is some info I can poke out of DDB
