It’d be interesting to know: a) does it appear at all? b) is it at the same offset in a page as we expect the fadt signature to appear (ie., offset 0xec0)? c) is it in a page we mapped previously via __acpi_map_table()? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
