    dx79to and i7 - 3930K not booting ubuntu




      I have dx79to using HyperX Blu 8GB 1600MHz ram and i7 - 3930k cpu and even with the latest 0559 bios update ubuntu doesn't boot if I enable more than 1 cpu in bios, kernel hangs at: Booting Node 0, Processors #1


      If I enable all cores system boots only if I set maxprocessors=1 or acpi=off kernel options


      The same thing happens if I use linux 3.2 (default 12.04LTS kernel) or 3.5 (backport from the latest ubuntu)

      Here is how the screen looks when it stops booting:


      Any ideas?
