There's Another Linux Kernel Power Problem

After last year discovering a major Linux kernel power regression that was widely debated until the Phoronix test automation software bisected the problem to get to the bottom of the situation, there's more active power regressions today on the Linux desktop. As I've mentioned on Twitter and in other articles in weeks prior there's a few regressions, but one of them for at least some notebooks is causing a very significant increase in power consumption. This situation that remains unresolved as of the Linux 3.7 kernel can cause the system to be going through about 20% more power.
