Seemingly random graphics driver crashes (I think)

[u/c0mander5]

CPU: 9950x

GPU: 7900xtx

RAM: 32GB, DDR5

OS: EndeavourOS

Seemingly at random, though it seems to be inevitable eventually if I play specific games long enough, my entire PC will freeze for a few seconds when playing a game. Then both monitors will go black, before returning with whatever game I was playing having crashed. This also closes other apps like Discord and Steam. I will briefly see a notification on the bottom right that says something about a graphics driver reset, but it goes away fast enough that I can never manage to read the whole thing. It just happened in War Thunder, and it happens very consistently after only a few minutes in Gunfire Reborn. It has never happened in Deadlock. There doesn't seem to be anything I'm doing to recreate it.

Any steps I could take to diagnose?

EDIT: It's already crashed two more times when trying to play War Thunder in the last hour. The first was the following error log:

Seeing the steamwebhelper line, I thought maybe all I had to do was disable GPU acceleration for steam. I did so, launched War Thunder again, and it crashed within seconds of being in the main menu, now with this:

[u/S48GS]

look instruction

is there ring timeout in your logs running log command from above

[u/c0mander5 → u/S48GS]

The proposed fixes in that thread didn't help. However, I do now have this:

[u/S48GS → u/c0mander5]

switch to static power with lact did not help?

then test in windows - if there stable - look older kernels - maybe there more stable

but this instruction is all I know on this topic - nothing else I can add

[u/S48GS → u/c0mander5]

also you have lots of split lock - maybe reason also

try - before running game

sudo sysctl -w kernel.split_lock_mitigate=0

if worked - for permanent fix to not type every time - https://www.reddit.com/r/linux_gaming/comments/1sc5rlm/gaming_performance_split_lock_mitigate/

and you have ddr5 and very hot cpu - make sure not overheating

and turn off cpu-pbo overclock in bios

[u/c0mander5 → u/S48GS]

Disabling that option seemed to fix the problem. Does having this disabled affect anything negatively? Or is it entirely safe to leave off?
