I got this on 4.8-STABLE from July 16 the other day while playing with dummynet configuration. I also managed to put tun0 into an unusable state on my firewall (running ppp(8) with netgraph pppoe on a dsl modem) by using ipfw pipe 1 bw config tun0 as suggested by the ipfw manpage. Whereupon nothing at all was transmitted through the pipe even after I reconfigured it back to the previous (working) setting. Restarting ppp, ifconfig down/up, had no effect and I had to reboot the machine to get it to transmit packets through the interface again.
