FreeBSD 9.1 RC3 fails boot on Ivy Bridge?

[Antonio Vieiro]

Hi all,

I just downloaded 9.1 RC3 (amd64 USB img) and I tried to install it on 
an Ivy Bridge CPU system (Gigabyte Z77 DS3H motherboard) without 
success: the system starts to boot but suddenly blows up and reboots.

I tried to boot with verbose mode but this does not help to determine 
the cause of the problem.

I was wondering if someone could shed some light into this.

TIA,
Antonio
