[Bug 1170836] Re: PCIe ASPM disabled while supported
Yes, this bug wasn't present before 11.04.
This is when kernel 2.6.38 that disabled ASPM for everyone came in, but
when this bug was solved for quite everyone, I've started seeing this
issue. Only noticed it recently, because before I was still passing
pcie_aspm=force when booting the kernel. And I still see a difference in
consumption of 2W between the two modes, going down from 14 to 12 on
idle when forcing ASPM to be enabled.

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.
