It has a single interface connected to a DSL modem. It has the stf nterface configured as its means of IPv6 connectivity. There is a non-trivial amount of IPv6 traffic hitting this machine. >Description: About every 7-10 days, the machine panics. Almost always the panic is in line 169 of ip_output.c, although a recent example had the panic in line 235. In every case, *ro was an IPv6 route, and ro->ro_rt->rt_flags was a crap address. I haven't really tried to tackle this one by myself yet. I'm instead hoping that someone else has already done the heavy lifting. >How-To-Repeat: Just wait a week. >Fix: Unknown. >Release-Note: >Audit-Trail: >Unformatted:
