somewhere near it. It's very important to find the errors and fix them, may be you have any ideas about the placement of error log during such boot (I mean coreboot+grub+xen) for resolving this problem as fast as possible, I can switch our company developers for research this thing, but I need the place for start
I suspect some issues in kern/i386/loader.S. missing initialization by the coreboot platform code, or some other weirdness in the real mode code. I'll take a look at it, but I can't give a time estimate.
If you're looking at it, as a first step you could do "set debug=all" on grub2's prompt, and look at the output (preferably over serial, so things don't disappear due to scrolling), maybe it gives some hints (no idea).
Regards, Patrick
