Hi, I just tried powertop (amazing tool), however I was shocked that around 70% of my laptop's wake ups are from " 67.5% (756.5) <interrupt> : extra timer interrupt" Google told me, I am not running tickless (although, my kernel is 2.6.22.4-45_1.cubbi_suspend2.fc6) and the chipset on my toshiba A105 satellite laptop seem to be ICH6 Family. Do I need that patch that forces enabling hpet timers?! If so, is there any (un)official fedora kernel that includes the patch, as I don't like to manually track kernel upgrades. I hope that patch will be integrated in mainstream fedora kernels soon. Regards
