I also got another one on a different machine: panic() at panic+0x164 rtfree() at rtfree+0x7c nd6_ns_output() at nd6_ns_output+0x48c nd6_timer() at nd6_timer+0x244 softclock() at softclock+0x22c ithread_loop() at ithread_loop+0x18c fork_exit() at fork_exit+0x94 fork_trampoline() at fork_trampoline+0x8 (core also available).
