This is fairly fresh stable/8 running under amd64, with pf, altq, openvpn (tun mode) and ipv6 enabled. So far I haven't found a way to reliably trigger the panic though. Because of the watchdog (the system is now on production) setting the system doesn't seem to be able to complete a minidump, will try textdump and see if it works. Suggestion on debugging? Is this a known (fixed?) issue by the way? Cheers, - -- Xin LI http://www.delphij.net/ FreeBSD - The Power to Serve!
