I am pretty sure I pissed of some eldritch deity because I have been chasing this laggy feeling I had with my pc for 2 months.
But in the past few days my desktop was getting very slow during installationand general use. At the same time my HDD activity indicator would be on all the time. Turning off the pc would shut it down and a few seconds later restart.
So I switched out Fedora for Pop OS and everything went fine for half a day and the problemen came back again.
When turning off the pc, right now, I got what you see in the picture.
So I would like to ask do I need to hire an exorcist or is hardware borked in someway?
Any help would be greatly appreciatie, so I would like to thank anyone even willing to look at my post.
EDIT: Well for anyone still interested, apparently it was something in the 6.5 series kernals that made my pc behave weird because with 6.6 kernal all of the problems vanished. I want to thank everyone again for all the suggestion and help diagnosing my problem.
It's possible that those three lines being logged rapidly is the major cause of the lag you've been seeing.
The cause of those ACPI messages could have to do with your motherboard manufacturer doing something "non standard".

Provides some instructions for masking the L09 GPE that you can try. I'd also follow their recommendations to do a memtest etc.
If the lagginess goes away after following the instructions then chances are the log messages were the cause of the lag. As for why the issue began in the first place? It's harder to say. It could be that a recent kernel update introduced some behavior which triggered the issue - so perhaps downgrading the kernel to a version from a few months ago is worth a try.
