Re: Kernel Panic in latest -CURRENT

I don't. My loader.conf consists of:

[root_at_storage ~]# cat /boot/loader.conf
autoboot_delay="3"
[root_at_storage ~]#

and sysctl.conf-
net.inet6.ip6.accept_rtadv=0
net.inet6.ip6.forwarding=1
net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1
net.inet.tcp.msl=7500
net.inet.ip.rtminexpire=2
