Whoa, that's a big initrd. Is Linux successfully mounting the initrd itself?
I remember there being something like a 4Meg limit on initrd size (by
default).
Why build with modules=all? Doesn't dep do what you want?

Sounds like you ended up building a XenLinux that used a different memory mode
to Xen itself. Xen builds with PAE enabled so that it can support large
memory hosts (> 4gig), but you need XenLinux to support PAE too if it's going
to work. I'm guessing you created this config from scratch, since the
default Xen build process will match PAE-ness.
Since your config must have had PAE disabled, copying the .config back to the
kernel tree will have replicated the same problem :-( Do make menuconfig /
xconfig and go to Processor Type and Features. Then in the "High Memory
Support" section choose 64GB. This will enable PAE. Rebuild the kernel,
(and modules, and initrd) then try that. It should boot...

It should run reasonably stably, once you get it running ;-)
