Kernel panic kmalloc

AnesCDev · 2021-12-26 17:58:24

Hello, recently my Arch installation is receiving crashes, i am searching information but i don't found nothing of my error, only documentation of kmalloc so... I need with that, for all the user that is reading that, thank you.
One thing, in the wiki the log example of the module have a section called BUG, but i don't found nothing of this in my log.
The log is:

It would be good to have more crashes to see whether there's a pattern (besides memory allocation)
In doubt, there's faulty RAM, https://wiki.archlinux.org/title/Stress … ing_memory
