Re: hpet timer patch for powertop

["Ahmed Kamal" <email ahmedkamal googlemail com>]

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 ;)

I have no idea where the kernel you have came from, but if you're
running x86_64 and you want tickless you'll need to upgrade to Fedora
8.  I don't recall if F7 has tickless for i686 or not, but F8 does for
sure.
