2.6.32.9 xen/stable booted on baremetal doesn't say anything about NX.

What happens if you boot with noexec=no on the kernel command line?

noexec=no didn't change anything.. still crashes. console output is the same as 
earlier.
I also checked the BIOS, it didn't seem to have any NX settings.

latest xen/master 2.6.31.6 seems to boot OK on this box, with the same Xen 
4.0.0-rc5 hypervisor.

successful bootlog of xen/master 2.6.31.6 here:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-xen-master-2.6.31.6-32b-works-log03.txt

xen/stable 2.6.32.9 boots OK on baremetal (without Xen).
Does it help to have a log of the boot on baremetal?

Here are a couple of xen/stable 2.6.32.9 crashing boots as Xen dom0,
with various debugging options, and also with "acpi=off":
Could you find what is at c0405dbe and around that area with gdb?

I think the problem is that there's something happening in kernel/head_32.S to test for NX and disable it if not present, which isn't happening on the Xen startup path. But I haven't investigated that yet.
