Unfortunately there seem to be some machines, where ACPI NVS is located at 64 MB, resulting in a conflict with the loaded kernel or the initial page tables built by Xen.As ACPI NVS needs to be accessed by the kernel only for saving and restoring it across suspend operations, it can be relocated in the dom0's memory map by swapping it with unused RAM (this is possible via modification of the dom0 P2M map).Shouldn't this paragraph be amended / re-written, as this was what made me ask for what is now patch 6?
Oh, indeed. Juergen
