--- Comment #9 from nicolas@deffayet.com ---
I confirm this bug on FreeBSD 11.0 RELEASE. Only igb interfaces are affecte=
d as
the issue don't occur with host using em instead of igb interfaces.
The crash seem to be related to a certain type and amount of packets.
Removing ALTQ support from kernel fix the issue.
It seem to be related to r303174. ALTQ seem to have not been supported with=
igb
interface according https://forums.freebsd.org/threads/48283/ and
https://lists.freebsd.org/pipermail/freebsd-pf/2016-August/008217.html
I suggest to test with r303174 removed:

Did you have the same issue with msix disabled ?
sysctl -w hw.pci.enable_msix=3D0
Not sure if this is true but MSI-IX and ALTQ seem to be incompatible.
