No, I mean the make and model of the machine. I have 3 different kinds
of dual 2.8GHz Xeon with tg3 NICs that Xen unstable works fine with. It
something specific to your particular machine, probably the BIOS. (BTW:
are their BIOS upgrades available?)

"make clean; make debug=y dist" should do it.

I expect you'll get an error message from Xen before the BUG in domain
crash. See where the error message comes from, and then add the
show_guest_stack to the appropriate path.
