[SOLVED] Kernel panic

When I turn on my PC, kernel panics and keeps outputting text. After a few restarts, the PC boots into Arch and everything is fine. After I turn it off, next time same thing. It was fine before yesterday, I think some packages are broken because on sunday I did sudo pacman -Syu which could be the reason for this behaviour. How do I fix this?

Re: [SOLVED] Kernel panic

Do you get the DRM panic screen (the QR code) and what are the extracted logs?

No DRM panic screen, just a black screen where every entry is formatted in [ time] message, and after every few seconds a bunch of new entries come up.

The stuff my PC outputs is really similar to the stuff shown in the first pasteimg. However, since the PC doesn't boot, I can't try out the solutions.

That is not true! You can add to kernel boot parameters 'module_blacklist=intel_oc_wdt' to your boot loader.

Okay, the issue seems to be fixed. After restarting the PC a few times, it booted and I tried all the things mentioned in Seth's reply and the next time I turned the PC on there was no panic.
Thanks to everyone who helped me get there!

Re: [SOLVED] Kernel panic

Nevermind, it's still there. However I have discovered that the only way to get it to boot from panic is to wait at least 1000 seconds and THEN restart/shut down and turn on.

In doubt link (please don't embed huge images) photos of that.

What do you see in the red cartouche?

Fwwi, editing the kernel commandline at the bootloader is transient - the changes will not "stick".
Check the wiki for configuring your bootloader.

I think my root partition might be full.

I think you might want to review blacklisting intel_oc_wdt again, though the next kernel update will have a patch.

Re: [SOLVED] Kernel panic

The issue has been solved. Turns out instead of using

modprobe.blacklist=intel_oc_wdt

in /etc/modprobe.d/filename.conf/ you're supposed to write

blacklist intel_oc_wdt

and the earlier one is for grub config. Thank you to everyone who helped or tried to.
