I've converted my ipfilter/ipnat system to ipfw/natd, and now the
problem is "solved".
However, your patch still gives me a *lot* of icmp_error: n_spare != n
messages. I also noticed that if I ping from that system, it pings
every 2 seconds instead of every second. The clock doesn't seem to be
affected, and changing kern.timecounter.hardware doesn't change the
situation.
