problem kernel: 6.13.6-arch1-1 , LTS has no such issues, currently using 6.12.18-1-lts

I use this everytime to set frequencies manually, but when i wake up from sleep it just doesnt work anymore, like i cant see any errors in  stdout or in dmesg

    # Set CPU frequency scaling with sudo
    for cpu in /sys/devices/system/cpu/cpu[0-9]*; do
        sudo bash -c "echo $max_freq > $cpu/cpufreq/scaling_max_freq"
        sudo bash -c "echo $min_freq > $cpu/cpufreq/scaling_min_freq"
        sudo bash -c "echo $governor > $cpu/cpufreq/scaling_governor"

Re: Unable to set cpu frequency after waking up from sleep

So what was the last kernel that it worked with?

Re: Unable to set cpu frequency after waking up from sleep

Also what are the acutal values you're writing in your script, when does that run and can you change the governor manually

echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Why are you setting the limits before the governor?
Does the same happen if you s2idle instead of S3 (deep) sleep?
