I use 5046A-XB with i7-930 as home workstation, running latest RELENG_8,
and I do not have the problem you noted. My BIOS is v1.1, USB legacy is
enabled.

I did noted one issue with hw, built-in firewire controller generated
too high interrupt rate, so I usually do not load firewire.ko unless
needed.
