I'd be surprised if we actually halted right at that message. I think it's just that most console output is suppressed by default, this particular message is KERN_ERR so it is not suppressed, and we hung somewhere later. Can you boot with "ignore_loglevel" and collect the entire console output? If you have a previous working kernel still installed, a corresponding log from it might also be useful.
