https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240608 --- Comment #1 from Harald Schmalzbauer <bugzilla.freebsd@omnilan.de> --- I guess this panic with an non-INVARIANTS kernel (wihtout any other debug OPTIONS) is related. This is happening quiet early after some traffic tests utilizing if_vmx(4). 12.1-prerelease without debug options: Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x0 fault code = supervisor write data, page not present instruction pointer = 0x20:0xffffffff806ffdc2 stack pointer = 0x28:0xfffffe0040557900 frame pointer = 0x28:0xfffffe00405579e0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (if_io_tqg_1) trap number = 12 panic: page fault cpuid = 1 time = 1568626299 KDB: stack backtrace: #0 0xffffffff8061f047 at kdb_backtrace+0x67 #1 0xffffffff805d33bd at vpanic+0x19d #2 0xffffffff805d3213 at panic+0x43 #3 0xffffffff80941d2c at trap_fatal+0x39c #4 0xffffffff80941d79 at trap_pfault+0x49 #5 0xffffffff8094136f at trap+0x29f #6 0xffffffff8091b92c at calltrap+0x8 #7 0xffffffff8061d904 at gtaskqueue_run_locked+0x144 #8 0xffffffff8061d568 at gtaskqueue_thread_loop+0x98 #9 0xffffffff8059b103 at fork_exit+0x83 #10 0xffffffff8091c96e at fork_trampoline+0xe #3 0xffffffff805d3213 in panic (fmt=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_shutdown.c:804 #4 0xffffffff80941d2c in trap_fatal (frame=<value optimized out>, eva=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/amd64/amd64/trap.c:943 #5 0xffffffff80941d79 in trap_pfault (frame=0xfffffe0040557840, usermode=0) at RELENG_12/src/sys/amd64/include/pcpu.h:234 #6 0xffffffff8094136f in trap (frame=0xfffffe0040557840) at /usr/local/share/deploy-tools/RELENG_12/src/sys/amd64/amd64/trap.c:443 #7 0xffffffff8091b92c in calltrap () at /usr/local/share/deploy-tools/RELENG_12/src/sys/amd64/amd64/exception.S:289 #8 0xffffffff806ffdc2 in _task_fn_rx (context=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/net/iflib.c:2614 #9 0xffffffff8061d904 in gtaskqueue_run_locked (queue=0xfffff8000206c100) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/subr_gtaskqueue.c:378 #10 0xffffffff8061d568 in gtaskqueue_thread_loop (arg=<value optimized out>) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/subr_gtaskqueue.c:559 #11 0xffffffff8059b103 in fork_exit (callout=0xffffffff8061d4d0 <gtaskqueue_thread_loop>, arg=0xfffffe00025fe020, frame=0xfffffe0040557ac0) at /usr/local/share/deploy-tools/RELENG_12/src/sys/kern/kern_fork.c:1065 #12 0xffffffff8091c96e in fork_trampoline () at /usr/local/share/deploy-tools/RELENG_12/src/sys/amd64/amd64/exception.S:1077 #13 0x0000000000000000 in ??
