Package: cpufrequtils Version: 008-2 Severity: important Tags: patch X-Debbugs-Cc: 1700011...@pku.edu.cn
Dear Maintainer, loadcpufreq is an init.d script of cpufrequtils to load cpufreq governors' kernel modules, but it does not work anymore after kernel 6.6. The reason is that: Current loadcpufreq does not support compressed kernel modules of cpufreq governors, because such modules end with ( for example ) .ko.xz rather than .ko, and this condition is not included in the script. After kernel 6.6 , Debian official kernal use config CONFIG_MODULE_COMPRESS_XZ , which means that all kernel modules are compressed with xz. So that now loadcpufreq does not work for current Debian kernel.Cpufreq governor modules will not be loaded. To fix the problem: We need to do just very little bit of changes of script to fix that problem. The revised script is attached here. Just replace /etc/init.d/loadcpufreq with this file please. -- System Information: Debian Release: 12.4 APT prefers testing APT policy: (700, 'testing'), (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable'), (100, 'bookworm-fasttrack'), (100, 'bookworm-backports-staging'), (100, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.6.9-amd64 (SMP w/16 CPU threads; PREEMPT) Locale: LANG=zh_CN.UTF-8, LC_CTYPE=zh_CN.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages cpufrequtils depends on: ii debconf [debconf-2.0] 1.5.82 ii init-system-helpers 1.65.2 ii libc6 2.36-9+deb12u3 ii libcpufreq0 008-2 ii sysvinit-utils [lsb-base] 3.06-4 cpufrequtils recommends no packages. cpufrequtils suggests no packages. -- Configuration Files: /etc/init.d/loadcpufreq changed [not included] -- debconf information: cpufrequtils/enable: true
