[Xen-devel] dom0 crash with unstable

["Bryan D. Payne" <bryan@xxxxxxxxxxxx>]

I'm trying to install Xen-unstable on a new machine.  At first boot,
I'm getting a dom0 crash.  The crash output is shown below.  The
complete console log is attached.

I pulled from Xen unstable yesterday (bd376919f03a tip), and built it
simply using "make world".  The machine has four Intel E5540
processors and 36GB of RAM.  In the BIOS, I have VT-d disabled, and
VT-x enabled.  Any suggestions on what steps I should take for
debugging this problem and getting dom0 to boot?

Thanks,
bryan
