Kernel panic: attempted to kill an idle task

[small ice]

Lenovo Legion 15ach66h with a Ryzen 7 6800H, Nvidia RTX 3070Ti, 32 GB RAM, two NVME disks - one used solely for windows, one used for Linux.
I swapped the network card to Intel AX200.
I have been using Arch so far, with GNOME. Recently I started having issues. Freezes, crashes back to login screen and the issue described - bsod with a kernel panic: attempted to kill an idle task.
Having not enough time to troubleshoot I decided to install FEDORA next to arch and use it for now.
While installing from live USB - I've encountered the kernel panic again.
I was able to install FEDORA, but while using it - kernel panic again.
I might have used Firefox in all of these situations, but otherwise - different systems, different kernels etc. and the same issue.
So far windows works ok.
What can be the source of my kernel panics? I'm guessing some hardware issue?

or drivers

I haven't installed any drivers on fedora on my own. Which driver could it be connected with? How to troubleshoot it?

[sleek sentinel]

i dont know

probably not the network drivers

[uncut timber]

get a memtestx86 iso and do a full RAM check

[sleek sentinel]

archinstaller has one

choose it in grub

[small ice]

will do, but id guess it would malfunction in windows as well.
hope its not ram failure with the current prices 😛

[small ice]

should it take this long?

[sleek sentinel]

yes

[small ice]

so... ram is good?

[sleek sentinel]

yes

hooray

idk why they suggested memtest

[small ice]

hmmm.... any other ideas then?

[sleek sentinel]

if this shit only happens in linux

its driver issue

[small ice]

how do you diagnose these though

and can both freezes and kernel panics be the same issue?
Sometimes before the kernel panic the blue screen theme like runs a
through the display, but I don't know if it's normal

journalctl

I've realized it's connected with laptops profiles (quiet, balanced, performance).
None of the issues exist on performance. It only happens in balanced or quiet. So I'm guessing Nvidia.

has caused issues for me at some point. it takes a while to run, but sometimes its worth ensuring that the hardware itself isnt failing via for example bad memory. though i do realize perhaps that was overkill if Windows ran fine. so that is geniuenly on me
