[Xen-users] bad pte error in domU

["Tait Larson" <tait@xxxxxxxxxxxxxx>]

I'm running the into the following error on one of my 
guest domains when I run a specific program
Bad pte = 004d10a0, process = findex, vm_flags = 100070, 
vaddr =

This error is output to the vm console over and over.

I'm using a xen kernel that I built from the 3.0.4.1 
source code.  I use the same kernel for both dom0 and 
domU.
Does anyone know what might be going on?  Any ideas how to 
debug this?
thanks,

Tait
