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.
