Panic during reboot involving softclock_call_cc(), nd6_timer() and nd6_dad_start()

[Trond Endrestøl]

Hi,

Has anyone else witnessed a panic during reboot involving 
softclock_call_cc(), nd6_timer(), and nd6_dad_start()?

The stack trace goes more or less like this:

db_trace_self_wrapper()
vpanic()
panic()
trap_fatal()
trap()
calltrap()
nd6_dad_start()
nd6_timer()
softclock_call_cc()
softclock()
ithread_loop()
fork_exit()
fork_trampoline()

This was last seen while transitioning from r345628 to r346220 on 
amd64 stable/12.
