Just to clarify this to me, and many others: I thought this was a Sandy Bridge problem, but I saw here that the test was not done on a Sandy Bridge processor, right?
At what point older family of processors this ASPM issue began? Or should I look to my motherboard to see if it has PCI Express slot, so it is affected?
For exemple I have a ThinkPad T61 with a Core 2 Duo T7300, do I get affected by this issue?
It's not at all Sandy Bridge specific but affects most hardware with PCi-E (particularly Intel hardware it seems, don't recall many reports of the issue on AMD hardware).

This is a BIOS-related problem which can happen on any CPU or chipset with PCIe support. For example there are Sandy Bridge computers without ASPM problems and Sandy Bridge computers with ASPM problems.
That's nice. Now the question is, when will it get merged? To which version of the kernel?
As the article states, most likely not till version 3.3 as the 3.2 merge window closed already. Maybe if this is significant enough and works well Linus could accept it for 3.2 perhaps in a point release such as 3.2.1

Phoronix = Fear Uncertainty and Doubt.

As for the "bug" - my thinkpad t420 - with the "regression" runs under 8 watts on battery.
My new Asus U56E, also with the regression is closer to 6 watts.
Simple configurations people, learn to Linux.
Could someone please explain me how to apply this patch? I use my UbuntuOneiric-powered pc just for "regular" activities like typing, surfing and listening to music. Not definitely the kind of power user you usually find on Phoronix. I've enabled RC6 in the grub file - it actually stretched my battery life, but - like several Sandy Bridge users - after this mod I'm experiencing video corruption. Does this patch will help me dealing with this disappointing issue?
Thanks in advance,
This patch would be an additional improvement in battery life.
