> Reader / writer lock error: lockdebug_wantlock: locking against myself Turns out this is an entirely different problem. The backtrace is lockdebug_more<-rw_enter<-fr_check<-pfil_run_hooks<-ip6_output<-nd6_ns_output<-nd6_output<-fr_fastroute<-fr_send_ip<-fr_send_reset<-fr_check<-pfi_run_hooks<-ip6_input<-ip6intr<-softint_dispatch.
I guess this might long be fixed. So I'll try building and running an -8 kernel.
