2019-07-29 23:57:10 Srijan Kumar Sharma description intel_pstate not working. CPU frequency fixed at 800MHz. I've tried to modify frequency using "cpufreq-set" and also by directly writing to files in "/sys/devices/system/cpu/cpu0/cpufreq/*" to no success. I tried different versions of kernel, it started working on 4.17.0 but stopped working soon. These are the versions I tested. 5.2.3 - Not Working 5.1.0 - Not Working 4.19.60 - Not Working 4.18.20 - Not Working 4.17.19 - Not Working 4.17.10 - Not Working 4.17.5 - Not Working 4.17.3 - Working 4.17.2 - Working 4.17.1 - Working 4.17.0 - Working 4.16.18 - Not Working 4.15.0 - Not Working Please let me know if anything else is needed. thanks ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-55-generic 4.15.0-55.60 ProcVersionSignature: Ubuntu 4.15.0-55.60-generic 4.15.18 Uname: Linux 4.15.0-55-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: srijan 2219 F.... pulseaudio CurrentDesktop: KDE Date: Sat Jul 27 11:34:10 2019 InstallationDate: Installed on 2018-11-25 (243 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0bda:5621 Realtek Semiconductor Corp.
