Arjan van de Ven reports on new PowerTOP features
on his blog. The new features live in the PowerTOP git repository
and require small kernel patches that will likely end up in 2.6.33. The features look at audio and SATA power management as well as "who is spinning up my disk":
"Using the perf kernel infrastructure, the git version of PowerTOP now has included the equivalent of the blockdump feature, and will report disk-waking application both in the regular interactive
view as well as in the diagnostic 'dump' mode.
