actually I'm still on FC6, and I'm using i686 CPU. The kernel is from tuxonice (suspend2) which is basically the same fedora kernel with suspend2 patches. Anyway, I thought all .22 kernels had tickless, dont they. If all of this + hpet patches will be in fedora8, I will be a happy fedorian ;) <div>On 9/22/07, Josh Boyer <<a href="mailto:jwboyer@jdub.homelinux.org"> jwboyer@jdub.homelinux.org</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">On Sat, 22 Sep 2007 15:04:07 +0200 "Ahmed Kamal" < <a href="mailto:email.ahmedkamal@googlemail.com">email.ahmedkamal@googlemail.com</a>> wrote: > 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.

I don't recall if F7 has tickless for i686 or not, but F8 does for sure. josh -- fedora-devel-list mailing list <a href="mailto:fedora-devel-list@redhat.com">fedora-devel-list@redhat.com </a> <a href="https://www.redhat.com/mailman/listinfo/fedora-devel-list">https://www.redhat.com/mailman/listinfo/fedora-devel-list</a> </blockquote></div>
