That at least is my conclusion after looking at this https://wiki.edubuntu.org/Kernel/PowerManagementASPM and a closer inspection of 'lspci -vvv'. The backported patch may be correct after all. It may be a candiate for centosplus kernel. If someone else wants to test: I can upload a kernel with this patch applied. -Michael
