Hi, I bumped into this. The following script will cause a kernel panic. jail -c vnet persist name=h0 jail -c vnet persist name=h1 ifconfig epair10 create ifconfig epair10a vnet h0 ifconfig epair10b vnet h1 jexec h0 ifconfig lo0 127.1 jexec h1 ifconfig lo0 127.1 jexec h0 ifconfig epair10a inet6 127::1 sleep 10 jexec h1 ifconfig epair10b inet6 127::1 Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x5732aff0 fault code = supervisor read, page not present instruction pointer = 0x20:0xc08b3f30 stack pointer = 0x28:0xe67ad7e8 frame pointer = 0x28:0xe67ad808 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 1999 (ifconfig) Physical memory: 1007 MB Dumping 59 MB: 44 28 12 Reading symbols from /boot/kernel/if_bridge.ko...Reading symbols from /boot/kernel/if_bridge.ko.symbols...done. done.
