At this moment, I'm not really sure. I'm using Intel DQ45CB with Bios
CBQ4510H.86A.0073.2009.0122.1353. Is anybody else using the same board
and having trouble with the I/O passthrough?

I've attached the connected console's output, can't really pick up
anything abnormal though, except that it just stops as you see it.
