I've just built Xen 3.1 x86 32 bit with PAE from source.

It runs most of my domUs just fine, windows etc, but it doesn't run a
Fedora Core 1 image.  It hangs at 100% cpu usage just after it frees
kernel memory.

If I mount the FC1 image on dom0 and chroot into it I get

  # chroot . /bin/bash
  Segmentation fault

I can chroot into it using ash.static indicating it is something to do
with shared libraries.  I suspect something to do with the mapping of
linux-gate.so.1 which the FC1 binaries need.

I can run this domain just fine off Xen 3.0.4.

I suspect I've missed out a kernel option or something like that but I
can't figure out what!

Any help most appreciated.
