When I flame up a domU I get the following pannic. Unable to handle kernel paging request at virtual address c54b4000 printing eip: c0147ff3 *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.
