[Xen-devel] Crash during boot in Debian lenny default dom0 kernel (2.6.26-2-xen-686)

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

I recenty tried to boot my Debian lenny distro on a newer Intel
Nehalem box using Debian Lenny's default xen kernel
(2.6.26-2-xen-686), and it crashed during boot.  Full log attached,
but the key info is here:

I tried doing a "binary search" to see where this was introduced, but
it fails the same way all the way back to c/s 20000.

The same kernel/hypervisor combination boots fine on a different box I have.
