--- Comment #15 from Dexuan Cui <decui@microsoft.com> ---
(In reply to pete from comment #12)
I installed a 11.2 VM on my local Hyper-V host with
http://ftp.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/11.2/FreeBSD-11.2-RE=
LEASE-amd64-dvd1.iso,
and can't reproduce the issue with MLX VF.

I also installed a 12-CURRENT VM on my local Hyper-V host with
http://ftp.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/12.0/FreeBSD-12.0-C=
URRENT-amd64-20180709-r336134-disc1.iso,
and can't repro any panic issue either ("#2: panic in vmbus_msghc_exec()" h=
as
been fixed by r336054)

I used mlx4en_load=3D"YES" in "/boot/loader.conf".

Need to figure out how to reproduce the issue...
