Alpine Linux - MS Hyper-V

Hello all

I discovered Alpine Linux last weekend and I was thrilled about it... I spent almost 20 hours playing and making scenarios about how to use of it...
So, today I tried to install it under M$ 2012 Server's Hyper-V... I know what you're thinking, but it's out of my control...
I already have installed FreeNAS to work with an (old) external NAS and an Arch Linux virtual machines...
I tried three different flavors of Alpine Linux (Standard, Virt and Extended) and I was not able to install it...
Error says :

[ some numbers, different each line ] NMI watchdog: BUG: soft lookup - CPU#0 stuck for 23s! [nlplug-findfs.553]

Can any one tell me how to proceed?

Thank you very much
Theodore
