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.
