Aha! That would explain why it was there - thank you for your sharp eye. BTW, are there any good materials on explaining _PSS, _PDC, _P.. and C-states and how to read the ACPI DSDT/SSDT to figure out what it has? One of my AMD boxes on baremetal finds the _PSS tables but when I boot under Xen it tells me it can't find it - and I am not even sure what they look like in the ACPI tables. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
