Bruno Pagani, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> ** Tags added: latest-bios-216 needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1170836 Title: PCIe ASPM disabled while supported Status in “linux” package in Ubuntu: Incomplete Bug description: I'm quite sure that my computer support PCIe ASPM (since I can force it to be enabled, and gain some watts on consumption), however the kernel disable it with this error: ACPI FADT declares the system doesn't support PCIe ASPM, so disable it I'm wondering is that could be an issue coming from this (a bit earlier in the kernel.log): ACPI Warning: 32/64 FACS address mismatch in FADT - two FACS tables! (20121018/tbfadt-394) ACPI BIOS Bug: Warning: 32/64X FACS address mismatch in FADT - 0xBB649F40/0x00000000BB64CD40, using 32 (20121018/tbfadt-521) I don't know what are relevant informations, so ask me if you would like any log or me to test anything. This is not something new, I have this issue for ages but never reported before. --- ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: archangegabriel 1964 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=94d188b9-7a1a-4ad4-9bf3-f6cecd5dca0e InstallationDate: Installed on 2012-12-16 (124 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Alpha amd64 (20121216) MachineType: ASUSTeK Computer Inc.
