But the DOpE window is opened? And is there something in the window?
I have no clear idea right now what could be wrong. Could you post your
.config, that you are using right now, again?
You could also try to disable PCI just for a test and see if it gets to
the point where Linux wants to mount the root partition and can't
because no driver is there. Maybe making earlyprintk to earlyprintk=keep
makes a difference too.
