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.
