I use `qjail` tool to manage jails. # first create jail, and use vnet for jail. qjail create -4 192.168.1.101 testjail qjail config -w em0 -v none testjail # repeat the follows command, page fault will happend on stop command, and system reboot. qjail start testjail qjail stop testjail System: FreeBSD 12.1-RELEASE amd64 Logs: Nov 24 21:44:09 FingerAge kernel: epair3a: link state changed to DOWN Nov 24 21:44:09 FingerAge kernel: epair3b: link state changed to DOWN Nov 24 21:44:52 FingerAge syslogd: kernel boot file is /boot/kernel/kernel Nov 24 21:44:52 FingerAge kernel: Nov 24 21:44:52 FingerAge syslogd: last message repeated 1 times Nov 24 21:44:52 FingerAge kernel: Fatal trap 12: page fault while in kernel mode Nov 24 21:44:52 FingerAge kernel: cpuid =3D 7; apic id =3D 07 Nov 24 21:44:52 FingerAge kernel: fault virtual address =3D 0x410 Nov 24 21:44:52 FingerAge kernel: fault code =3D supervisor read= data, page not present Nov 24 21:44:52 FingerAge kernel: instruction pointer =3D 0x20:0xffffffff80baff2d Nov 24 21:44:52 FingerAge kernel: stack pointer =3D 0x28:0xfffffe00403c3940 Nov 24 21:44:52 FingerAge kernel: frame pointer =3D 0x28:0xfffffe00403c39c0 Nov 24 21:44:52 FingerAge kernel: code segment =3D base 0x0, limit 0xfffff, type 0x1b Nov 24 21:44:52 FingerAge kernel: =3D DPL 0, pres 1, = long 1, def32 0, gran 1 Nov 24 21:44:52 FingerAge kernel: processor eflags =3D interrupt enabl= ed, resume, IOPL =3D 0 Nov 24 21:44:52 FingerAge kernel: current process =3D 0 (thre= ad taskq) Nov 24 21:44:52 FingerAge kernel: trap number =3D 12 Nov 24 21:44:52 FingerAge kernel: panic: page fault Nov 24 21:44:52 FingerAge kernel: cpuid =3D 7 Nov 24 21:44:52 FingerAge kernel: time =3D 1574603049 Nov 24 21:44:52 FingerAge kernel: KDB: stack backtrace: Nov 24 21:44:52 FingerAge kernel: #0 0xffffffff80c1d297 at kdb_backtrace+0x= 67 Nov 24 21:44:52 FingerAge kernel: #1 0xffffffff80bd05cd at vpanic+0x19d Nov 24 21:44:52 FingerAge kernel: #2 0xffffffff80bd0423 at panic+0x43 Nov 24 21:44:52 FingerAge kernel: #3 0xffffffff810a7dcc at trap_fatal+0x39c Nov 24 21:44:52 FingerAge kernel: #4 0xffffffff810a7e19 at trap_pfault+0x49 Nov 24 21:44:52 FingerAge kernel: #5 0xffffffff810a740f at trap+0x29f Nov 24 21:44:52 FingerAge kernel: #6 0xffffffff81081a0c at calltrap+0x8 Nov 24 21:44:52 FingerAge kernel: #7 0xffffffff80ccd5e1 at if_detach_internal+0x261 Nov 24 21:44:52 FingerAge kernel: #8 0xffffffff80cd490c at if_vmove+0x3c Nov 24 21:44:52 FingerAge kernel: #9 0xffffffff80cd48b8 at vnet_if_return+0= x48 Nov 24 21:44:52 FingerAge kernel: #10 0xffffffff80cfe2b4 at vnet_destroy+0x= 124 Nov 24 21:44:52 FingerAge kernel: #11 0xffffffff80b98870 at prison_deref+0x= 2a0 Nov 24 21:44:52 FingerAge kernel: #12 0xffffffff80c2fa74 at taskqueue_run_locked+0x154 Nov 24 21:44:52 FingerAge kernel: #13 0xffffffff80c30da8 at taskqueue_thread_loop+0x98 Nov 24 21:44:52 FingerAge kernel: #14 0xffffffff80b90c23 at fork_exit+0x83 Nov 24 21:44:52 FingerAge kernel: #15 0xffffffff81082a4e at fork_trampoline= +0xe --=20 You are receiving this mail because: You are the assignee for the bug.=
