I have an issue with a computer, where it randomly crashes sometimes, completely out of nowhere, and has to be force-shutdown to be used again. After looking into the kernel logs using journalctl -k -b -1, a possible culprit was spotted, as seen in the kernel log below. It seems that when processing the __x64_sys_read function, which directly corresponds to the read syscall to read from file descriptors, a page fault is produced that causes a crash and kernel panic. I strongly suspect this issue to be hardware-related. Is this issue caused by broken RAM or a broken disk? Is it a software issue with the kernel or a driver?
The kernel log:
