Looking at the two boot logs, the PCI resources allocated are very
different. My big worry is about the reported differences on the IRQs in
use. I'm not sure what more help I can be. I doubt that the missing CPU
is affecting things too much, I just think that this board support code
simply needs fixing. It would be helpful if anyone knew of any previous
revision where it used to work?
Did you try Carl-Daniel's suggestion of booting with 2GB or less?
