>Description:
On virtual box the same actions works.
On hyper-v 2012 OS these action leads to kernel panic.

I can't paste a text from vurtual machine, but i can provide screenshots, but not here, as i see there's no such ability. So ask me and i send it to email.

The similar errors, as i see, we can see here:
http://lists.freebsd.org/pipermail/freebsd-virtualization/2013-October/001679.html
and here

>How-To-Repeat:
Download the 10.0 release
pkg install subversion
svn checkout http://svn.freebsd.org/base/stable/10/ /usr/src
cd /usr/src
make -j4 buildworld
make -j4 buildkernel KERNCONF=GENERIC
mergemaster -p
make installkernel KERNCONF=GENERIC
make installworld
mergemaster

reboot
>Fix:
Exclude fron kernel config next string:
device          hyperv          # HyperV drivers 
but i don't think it is a fix.
