Hi Christopher, thanks for replying. This still happens. I just updated to deb:linux-image-2.6.38-14-generic (version 2.6.38-14.58), installed linux-crashdump and tried to start powertop. Crash dump attached.

Run powertop. 2. Stare at frozen screen. 3. ??? PS .Not sure if it's related to other freezes and kernel panics I experience sometimes.
