Still an issue I think...

Architecture: amd64 (Turion dual core mobile)
Video: AMD mobile HD3200 (open driver)
Driver: Source: xserver-xorg-video-ati
Version: 1:6.14.99~git20111219.aacbd629-0ubuntu2
Unity: Version: 5.8.0-0ubuntu2

with unity 3d I have an extra 60 processor wake-ups per second while doing absolutely nothing (stable, like a framerate) due to interrupt 18 (radeon HD3200 open driver) on top of the more or less 60 regular wake-ups

with unity 2d I don't have these int18 wakeups at all, only the regular ones.

did the patch only work for sandy-bridge stuff ?

also, possibly related, the PS2-mouse/touchpad hits an incredible max of over 500 wakeups/sec (which, of course, is a bit over the top with a video framerate of 60 ) could and/or should this be capped at exactly the framerate (or half of it) ?
