Hi, I can not capture the full failing boot log.
The kernel panic, and shift + pageup does not work. 

With output to serial console, the problem goes away.

I think with an initrd, I can reproduce the problem and capture the full 
failing boot log.
But with an initrd, there's no problem. Every thing works fine.

Thanks.
