[Xen-users] problems when networking runs up.

When I flame up a domU I get the following pannic.

Unable to handle kernel paging request at virtual address c54b4000
printing eip:

*pde = ma 01413067 pa 00013067
*pte = ma 00000000 pa 55555000
[<c0146503>] pte_alloc_map+0x128/0x151(XEN) Domain 0 shutdown:
I have tried searching the list archive but not had much luck finding any problem descriptions that seem related to this. 
Any help would be appreciated.
I have one system that runs fine. it is a single processor system on a generic motherboard.

the second that is crashing is a Tyan Tomcat. The CPU supports hyperthreading, but not that shows in cpuinfo.
