Xen users - Feb 2009 - HVM Restore failed : invalid device model signature read

I have Debian lenny Dom0 and Ubuntu HVM domu.
When I restore the VM snapshot, the VM shows up in paused state for a bit.. and
then I get the following error
"Fault 2:invalid device model signature read"

stack :
[2009-02-03 19:08:31 2502] ERROR (XendDomain:1136) Restore failed
Traceback (most recent call last):
