On Fedora 39. Basically when I plug in a microSD into my framework expansion card it always reports 100% usage on powertop even if I’m not using or accessing it. I don’t really see why this should be happening. Any way to limit the power that the microSD card uses? Tried with both a PNY and a Samsung microSD, same result. (Although the PNY reported 4 watts instead of 3.5 watts)

    Edit: I misunderstood. 100% core use all the time for no reason isn’t normal.

    My first thought would be driver or kernel bug, or a runaway parent process.

    For a fuller view of resource usage, I would use either atop or htop. While debugging, you can prlimit with the pid flag to save battery.
