I'm seeing this on an x440 with SLES 9, using changeset 6003.
Interestingly, I make it past this point if I specify mem=4G at boot.

The crash happens very early on when booting Xen so I don't
think Linux can be the problem.  I tossed some printk's into
paging_init() (that's where the last line of output came
from in the original boot log) to see if it dies in that function.

It seems to die somewhere in this code as I see the first printk message,
but not the last as it is about to exit:

I strongly doubt anyone has tested PAE Xen on a >4GB machine. You are trailblazing. ;-)

I think Gerd's test box isn't even SMP.

We have a 8GB box we could do some testing on...
