The ACPI 1.0 specification wants us to put devices into low power states after executing the _PTS global control method, while ACPI 2.0 and later want us to do that in the reverse order. The current hibernation code follows ACPI 2.0 in that respect which may cause some ACPI 1.0x systems to hang during hibernation (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). Make the hibernation code execute _PTS before putting devices into low power states (ie. in accordance with ACPI 1.0x) with the possibility to override that using the 'acpi_new_pts_ordering' kernel command line option.
