Thanks for your work.
I tested this, and it actually looks to have made things worse, if anything.
Here are four powertop logs, each run with -d -t 300. Prepatch is the
stock ubuntu kernel as of today, postpatch is your build. Without
load is standard gnome stuff and xmonad running, plus daemons, and
nothing else. With load adds several browser tabs, one of which
downloading playing a long youtube video throughout.
You'll notice that things get worse postpatch in both scenarios, but
probably not to a statistically significant degree.
Perhaps I don't suffer from this bug?
If you get the chance, since you already have the machinery to make
debian builds (and I've never actually figured out the proper way to
do this for the kernel), do you think you could build me a copy of the
same thing, but with the timer frequency set to 100Hz? Feel free to
just mail me debs rather than uploading them to the ppa, if you can do
this for me.
