It may have been as early as the upgrade to 16.04. I remember having some performance/overheating issues at that time so I disabled intel_pstate for a while; but I never fully diagnosed the issue. The 17.10 install was a fresh install though, I wiped the system. I'll try the new kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1738534 Title: Processor turbo dsiabled/throttled after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1738534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

As a workaround, I created a post-resume script that runs the above commands at /lib/systemd/system-sleep/throttle-workaround.

[Bug 1738534] Re: Processor turbo dsiabled/throttled after suspend
Just tried another scenario. If I do the full power cycle while on battery power, then it boots up with turbo disabled and frequency locked. This command then seems to work (cpupower then reports turbo is active/supported): sudo x86_energy_perf_policy --turbo-enable 1 But this command has no effect: sudo cpufreq-set -r --min=0.8GHz --max=3.0GHz (Where, int he previous scenario, it did work.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1738534 Title: Processor turbo dsiabled/throttled after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1738534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
