Hi guys,
I'm experiencing reproducible kernel panics when launching VirtualBox VM
with bridged network. Panic occurs right after VM is launched and
reproduces every single time.
kernel/world: FreeBSD 11.0-STABLE #0 r312012
amd64 + 64Gb RAM + zfs
NIC: em0: <Intel(R) PRO/1000 Network Connection 7.6.1-k> mem
0xdf100000-0xdf11ffff irq 16 at device 31.6 on pci0
$ pkg info | grep virtualbox
virtualbox-ose-5.1.12
virtualbox-ose-kmod-5.1.12
both were recompiled after latest kernel/world rebuild.
$ kldstat | grep vbox
5 3 0xffffffff818ef000 83d80 vboxdrv.ko
9 2 0xffffffff82225000 29ef vboxnetflt.ko
12 1 0xffffffff8223a000 3f76 vboxnetadp.ko
Custom kernel with
options VIMAGE
device epair
device if_bridge
added for experimenting with jails (not sure is this matters, and box is
running jails though just in shared ip mode, no vnet/vimage).
Here are some details from coredump:

Has anyone encountered this? Do you know if this is a bug or just
misconfiguration leading to
an unpleasant panic? Any hints would help.
Thank you.
