Two scripts in cpufrequtils are needed to run debian pc/laptop correctly. They are /etc/init.d/cpufrequtils and /etc/init.d/loadcpufreq .
These two SysV scripts are used to load kernel modules of cpu frequency scaling governors correctly. For some other distributions, because they build scaling governors into kernel so they do not have such problem. However, Debian kernel build them as module so that we need a script to modprobe them. These two scripts are broken after kernel 6.6 because changes of Debian kernel conifg. You can see this problem at #1060238 ( https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1060238 ) . Kernel team does not think they need to change config from m to y, so that here we still need some scripts. Now there are three options: 1. Keep the package cpufrequtils and fix the bug ( I have written a patch to fix it) 2. Move the scripts to another package and fix the bug 3. Write new scripts to modprobe the modules, hopefully we can get rid of sysV scripts. Thanks
