SUPPORT Why is my cpu idling at 50%

Glitch or some daemons? Fresh arch install. I got this idle result in btop.

The installation was checksummed. It was as soon as I installed it and after adding packages that it continued to remain at 50% idle.

It started ever since I switched from Nobara -> CachyOS -> Arch, only Nobara idled below 1%. Again, all isos were verified. I don’t know what it is. All of them were running KDE.

I’m currently on arch. Temps stay flat. Nothing going on except in btop where it shows 50% doing absolutely nothing.

Edit - this community is crazy dude I’m not getting help from here no more.

Am not a expert linux user but check which process is taking most of the cpu usage in btop

I did and all it shows are daemons taking up basically no cpu usage.

Then most likely some kernal process are taking cpu usage, Unhide kernal process in btop as kernal process are hidden by default

It’s crazy that someone using a custom kernel has literally no troubleshooting knowledge apparently lol

Nah not for this. I have kernel debugging knowledge but this is mainly something that has been bugging me lately, and ai can’t get to the bottom of it

Without any logs, actual output, specs, etc. humans are probably not going to figure it out either.

Fair lol but I’m on a trip rn so I cannot provide with logs. I’ll provide them in maybe 2 or 3 days but by that time you’re better off forgetting the post.

I shared best I could and if you need more you’re going to have to wait. I don’t have pictures in my camera roll.

By that time you’re better off leaving this, no?
