Jasper, 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 by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Title:
Turbo mode on i7 is not enabled upon resume
Status in linux package in Ubuntu:
Incomplete
Bug description:
Turbo mode is not enabled upon resume from suspend.
To enable I must issue:
``echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo
echo 1 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo
echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo``
I would expect that Turbo was re-enabled by default from resume.
I created a script in /usr/lib/pm-utils/sleep.d/ to issue the above
commands, but clearly that mechanism is depreciated.
I am reporting this bug against systemd as I assume that it is
managing the running of startup and resume scripts.
A quick hack solution would be appreciated in the short term.
