Kernel panic on linux 6.9 manjaro

It is impossible to say - your system looks fairly ordinary to me

It could be caused by the plymouth nvidia combination - but as I don’t run Nvidia I cannot say.

As you are using a AMD 7735 APU, I suggest you use a newer kernel - usually better support for AMD

On stable branch you linux 6.10.0 is the latest.

On unstable branch there is Nvidia 555 and Linux 6.11-rc1

The use of screenshots

Do not post images or screenshots as part of your topic. The forum is a technical forum not an image gallery.
Forum Rules - Manjaro

I removed you screenshot and pasted you systeminfo from your link.

Please avoid images in the future.

The forum search engine cannot index images - they are not searchable like text - and finding information in other topics is a must on this forum.
