Since the last kernel update, the power use of my laptop idle went from 11W to 14W. It seems the kernel patch; which also comes with kernel 3.2.5, prevents the trick of boot option "pcie-aspm=force" to work, while not activating it on my hardware. kernel 2.6.38.8-6 dmesg: PCIe ASPM is forcedly enabled ACPI FADT declares the system doesn't support PCIe ASPM, so disable it kernel 2.6.38.8-10 and 3.2.5 with Cauldron dmesg : PCIe ASPM is forcedly enabled ACPI FADT declares the system doesn't support PCIe ASPM, so disable it ACPI _OSC control for PCIe not granted, disabling ASPM

This message is a reminder that Mageia 1 is nearing its end of life. In approximately 25 days from now, Mageia will stop maintaining and issuing updates for Mageia 1. At that time this bug will be closed as WONTFIX (EOL) if it remains open with a Mageia 'version' of '1'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Mageia version prior to Mageia 1's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Mageia 1 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Mageia, you are encouraged to click on "Version" and change it against that version of Mageia. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Mageia release includes newer upstream software that fixes bugs or makes them obsolete. -- Mageia Bugsquad
