Kernel 6.8.x constantly barfing out errors, randomly freezing or panicking

This has been happening recently on my Thinkpad T480. Since kernel 6.8.x it's been spitting out these vague errors at a 1-second interval. Eventually (with no apparent correlation to any other events) it'll freeze up or panic.

This happens both on Linux LTS and Linux Hardened. When running your LTS 5.15 kernel this doesn't happen.
I have a feeling I should bring this to the kernel maintainers, but I thought I'd ask here first.

I run Artix with s6.

Here's a long snippet of dmesg:

Here's a shorter snippet with some long repeating lines taken out:

If anyone has any idea what the hell to do about this, please do let me know. Thank you.

Kernel series 6 sucks.

After a recent update, it somehow magically went away.
