Hi all I've checked the latest 2.1-DEV and build both kernel and userland, then it crashes at ipv6=YES in rc.conf It shows <- SMP XXX and ip6_setsock... ip6_setsock... rip6_... ... lwkt_exit Does DFly support ipv6? My box is AMD 3600 and NForce550, and I got the ipv6 with a 64 prefix in college. best wishes whisper :)
