#16 0xc01f45b5 in arptimer (ignored_arg=0x0) at /usr/src/sys/netinet/if_ether.c:152
        rt = (struct rtentry *) 0x0
        s = 4194304
        la = (struct llinfo_arp *) 0x620000
        ola = (struct llinfo_arp *) 0x0
#17 0xc01a8259 in softclock () at /usr/src/sys/kern/kern_timeout.c:131
        c_func = (void (*)()) 0xc01f4580 <arptimer>
        c_arg = (void *) 0x0
        c = (struct callout *) 0x0
        bucket = (struct callout_tailq *) 0xcf0e3bd0
        s = 4194304
        curticks = 8640950
        steps = 0

I wonder if this is related to the (security-related) ARP changes from a few weeks ago.
