From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

this has happened on my device a lot of times now, whenver I start my laptop, I have installed arch on it. can anyone please tell me what is it and how to fix this? and I am a newbie.
You have a kernel panic.
If you're a noobie, figure out why.
Place to start: What is your kernel doing when it crashes?
Tip: System logs are your friend.
Hint: recovery root.
I suppose I fixed it. I checked logs, there were some errors with /etc/fstab.
I opened sys logs last time and didn't get shit, but okay will do again and get back to you.
syscall -> asm -> page_fault
This a native machine code execution that crashed in your system. Could be an instruction that your CPU doesn't understand (because the instruction is newer than your CPU, example: AVX512), or because your hardware returns an error when this instruction is executed (RAM issues?). Too difficult for me to understand this ASM crash.
I don't think it's some cpu issue because I used arch for sometime on my another laptop which is poorer in terms of hardware and cpu than current one. But again I might be wrong, will try to understand if this happens again.
The OS splits memory into pages and assigns the pages to applications. A page fault usually means one of two things:
You can check your memory with Memtest86. Some LiveCDs come with it. If it's a programs fault you can only try other software if possible.
Does it say anything above that? Look for the last line written in plain English. That should be what Linux was trying to do before it panicked.
Issue is solved. Thanks though.
