Incase you need it "fixed" now, here's a workaround.
Throw this in like /etc/hotplug.d/iface/99-6in4-fix.
Not tested, chopped down version of what I run for another reason.
The loop isn't 10 seconds. The failed ping takes about 7 seconds. So
this tests the wan int for about 1m30s.
#!/bin/sh
if [ "$ACTION" = "ifup" ] && [ "$INTERFACE" = "wan" ]; then
fix6in4 () {
. /lib/functions/network.sh
network_get_device wanIF "wan"
loop=0
ping="/bin/ping -W 3 -c 5 -q -I $wanIF"
until [ "$loop" -gt "10" ] || $ping 8.8.8.8 > /dev/null 2>&1; do
let loop++
sleep 1
done
if [ "$loop" -lt "11" ]; then ifup wan6
else /usr/bin/logger -t 6in4-fix -p user.notice "Failed to
reset 6in4 tunnel."; fi
}
fix6in4 &
fi
