[Xen-devel] Re: [Fedora-xen] 2.6.31-1.2.65.xendom0.fc12.x86_64 crash on
Well, for some reason, the BIOS had NX disabled by default. After
enabling, I can now get further. I've attached the output I'm now
seeing. Could this now be related to the myoung kernel?
Many thanks.

This looks like something trying to set the NX bit in a mapping, which
should be fine on this processor. Could it be disabled in BIOS or
something?

That should of course have been

Hm, OK. Maybe the problem is that we haven't enabled NX in EFER at
that
early point. I'll cook something up.
