Since Arch Linux is not popular among kernel developers I just tested Fedora 10 Live-CD (KDE) and I can reproduce the exact same problem, even if Fedora 10 has kernel 2.6.27 and for me the problem appeared in .28 (but I guess Fedora adds many patches, so probably the "guilty" commit was backported to 2.6.27.5-117-FC10-i686). Steps: - Boot into Fedora 10 Live CD (obviously, into the default graphical mode) - Install Powertop (yum install powertop) and run it - I get about 60 wakeups per second from i915@pci.... leaving the system idle - Switch to console and back to X. The wakeups are gone. I hope that helps.
