Hello,
-STABLE r203907 (amd64) reliable panics when I connect my FreeBSD box to
a Linux box using Firewire and do:
linux% ifconfig firewire0 up 10.0.0.1 && nc -l -p 9123
fbsd% ifconfig fwip0 up 10.0.0.2 ; echo hello | nc 10.0.0.1 9123
Details follow:
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
