[Bug 1252462] Re: CPU turbo mode frequency issue with Kernel 3.11 under Saucy 13.10 (Intel I7)
Some update: After some search, i discovered that the intel_pstate seems to have to be enable running default Ubuntu kernel adding : /etc/default/grub Add: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash intel_pstate=enable then sudo update-grub After reboot, i can see the good configuration i was seing it with kernel 3.12: cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to cpuf...@vger.kernel.org, please. analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 0.97 ms. hardware limits: 800 MHz - 3.10 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 3.10 GHz.

With kernel 3.12 we don't have to manually enable intel_pstate... not sure most user would think about that to take all the benefit of last computers... ** Description changed: Hi, I am opening this bug because i'm suspecting my processor not to run under good frequencies under 13.10 with default kernel 3.11.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1252462/+editstatus and add the package name in the text box next to the word Package.
