Errors installing FreeBSD 10.1 amd64 under Hyper-V 2012 R2

[C. L. Martinez]

Hi all,

 I have installed a FreeBSD 10.1 amd64 under a Windows 2012 R2 Hyper-V
host. This FreeBSD vm is configured as Generation 1 and I see a lot of
errors like this:

 Is this an expected behavior?? Do I need to reconfigure something??

Thanks.
