Package: linux-image-4.14.0-0.bpo.3-amd64
Distro: Debian 9 Stretch
When I try to set CPU frequency to the minimum, it doesn't work. This works
perfectly with kernel 4.9.5 (but with 4.9.5 I cannot hibernate).
Steps to reproduce the bug:
Have this in your grub: GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable"
su
cpufreq-set -c 0 -g userspace
cpufreq-set -c 0 -f 400MHz
With kernel 4.9 this resulted in the cpu running cold and silently at 400
MHz (check with cpufreq-info or with mate indicator applet).
After updating to 4.14 (linux-image-4.14.0-0.bpo.3-amd64 and corresponding
linux-header) the above mentioned use of cpufreq-set sets a variable
frequency policy.
Remark: this is happening too in Ubuntu 16.04 with kernel 4.10 and 4.13, so
probably the bug was introduced in 4.10.
(remark: reportbug is crashing in my system and that is why I send an
email. See screen capture at

Please send further instructions to provide any kind of log you need.
Thanks.

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
