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
