Package: cpufrequtils Version: 008-1 Followup-For: Bug #666499 I'm also seeing this on a Dell Studio XPS 8100
The first CPU gets the correct frequency settings on resume, but the others don't. On boot - set via /etc/default/cpufrequtils: ENABLE="true" GOVERNOR="ondemand" MAX_SPEED=2133000 MIN_SPEED=0 # cpufreq-info | grep 'be within' current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.13 GHz. After a suspend-to-ram, then resume: # cpufreq-info | grep 'be within' current policy: frequency should be within 1.20 GHz and 2.13 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. current policy: frequency should be within 1.20 GHz and 2.80 GHz. i.e. first CPU retains settings, others revert to boot-time defaults. I don't know what code (kernel/userspace/BIOS) should be responsible for restoring the CPU frequency settings after resume, but it's not working on this system the Jessie kernel. As a workaround I created this script as /lib/systemd/system-sleep/cpufrequtilsrestart #!/bin/sh case $1 in pre) # Do nothing exit 0 ;; post) echo "Setting CPU frequency preferences following system resume" systemctl restart cpufrequtils.service ;; esac -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages cpufrequtils depends on: ii debconf [debconf-2.0] 1.5.55 ii libc6 2.19-13 ii libcpufreq0 008-1 ii lsb-base 4.1+Debian13+nmu1 cpufrequtils recommends no packages. cpufrequtils suggests no packages. -- debconf-show failed -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
