Have you tried ram_check() in auto.c? Sounds like you may have some  
memory initialization problems like I was having. You can try this:

1. Enable debugging output in raminit.c, build and run to get the bootlog.
/* Uncomment this to enable debugging output. */

2. As root with the factory bios do a lspci -xxx.

3. Compaire the 00:00.0 Host bridge from lspci -xxx to the Northbridge  
following SDRAM init: PCI: 00:00.00 from your bootlog. Especially the  
DRB registers. I had two DRB registers that were supposed to be  
reserved but they are not. I set those and boom it booted:-)

Hope that helps.

Thanks - Joe
