UbUK, best bet in maximizing traction with upstream is test latest mainline kernel (now 5.2-rc6). If still reproducible with the latest mainline kernel, advise of this on a follow up of https://marc.info/?l =linux-pm&m=141741418405179&w=2 (TO Rafael J.

Hello Rolf I originally filed this bug in 2014. Sadly, nothing was ever done to resolve the issue. Although I am still using the same laptop I am now running Ubuntu 18.04.2 LTS with 4.15.0-52-generic kernel (all updates have been installed). The same bug still exists. So I don't think it would be appropriate to close it.

[Bug 1396291] Re: Maximum CPU frequency incorrect and there is no CPU scaling
I don't know if this occurred in a release prior to Trusty so I downloaded 12.04.3 LTS (Precise Pangolin) - the distro linked to in your post - and ran it from a USB stick. The short answer is that the problem also exists in Precise. Slightly longer answer - the CPU is recognised/named correctly but it only runs at 2.4 Ghz and there is no CPU scaling. I could not get "cpupower frequency-info" to run (as per original bug report) but running "cpufreq-info" in a terminal returns: cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to cpuf...@vger.kernel.org, please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 2.40 GHz - 2.40 GHz available frequency steps: 2.40 GHz, 2.40 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 2.40 GHz and 2.40 GHz.

[Bug 1396291] Re: Maximum CPU frequency incorrect and there is no CPU scaling
UbUK, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.18-rc6 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

apport information ** Description changed: I have an Acer Aspire 5720 and it is set up to dual boot Vista and ubuntu 14.04 LTS. From new the laptop came with an Intel T7300 2.00 Ghz CPU and 1 GB DDR2 RAM. A few weeks ago I upgraded to 4 GB RAM, which works perfectly, and a few days ago I upgraded to an Intel T9300 2.5 Ghz CPU. The BIOS (up to date), Vista and ubuntu all recognise the CPU correctly as: "Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50 GHz". Vista allows the CPU to run correctly at up to 2.5 Ghz and will step the CPU speed lower when not needed, depending on which power settings are chosen. The problem is that ubuntu will only allow the CPU to run at a fixed frequency of 2.4 Ghz, which is incorrect as it's a 2.5Ghz CPU, and there is no stepping to lower the CPU frequency when max frequency is not needed. "cpupower frequency-info" in a terminal returns: analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 2.40 GHz - 2.40 GHz available frequency steps: 2.40 GHz, 2.40 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 2.40 GHz and 2.40 GHz.

I have also installed CPU Frequency Scaling Indicator (which shows only 2.4 Ghz and 2.4 Ghz (turbo mode) as available frequencies) and I have also tried TLP but nothing makes any difference. According to this website: http://www.phoronix.com/scan.php?page=article&item=mobile_penryn&num=3 the T9300 CPU should have the following frequency steps: 2.50 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz and 800 MHz. - I have spent days trawling the internet for a solution but to no avail. - Hence filing this bug report in the hope a solution might be found. + I have spent days trawling the internet for a solution but to no avail.

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/1396291/+editstatus and add the package name in the text box next to the word Package.
