The screen output goes by so fast I cannot tell if this call trace is in 
it.  I'm still waiting for a serial card to show up so I can capture the 
output.  When I boot the 2.6.32.10 kernel under Xen pv_ops dom0 it will 
either start showing "soft lockup" bugs or it just hangs after XENBUS: 
Unable to read cpu state.  If I boot the 2.6.32.10 kernel without Xen 
then it just hangs - no output at all.
