It seems that only ICMPv6 packages panic the kernel, sshing to the box on IPv6 keeps it alive, but ping6 and traceroute6 to the box kill it in about 10 seconds.

When i traceroute6 my 2.4.4 box on my local lan, the 2.4.4 box panic's after about 10 seconds. The traceroute6 completes on the other box.
2.4.3-ac14 doesn't experience these problems. Only 2.4.4 (with or without ac{1,2}) panics
