It seems like a kernel bug. It has happened before. I am currently on 5.18, I will try with 5.19 on my laptop and see what happens.

Hello, the same thing is happening to me ([Errno 16] Device or resource busy) but in my case is when I will disabling any core, it's Kernel 6.0.6. Is there any chance that it can be fixed in the future? I like the easy steps to for example disable cores, changing profiles or just setting up a new profile with few little knowledge.

Anyway, thanks for this excellent project.

I have upgrade my kernel to 6.0.0 and I get the same error. I will try to troubleshoot it.

So, if the cpu is disabled the CPU files in sysfs cannot be read. I will change the logic so it skips reading the values for disabled CPUs.
