issue with starting on my laptop having arch installed. [SOLVED]
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.
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.
Disclaimer: I don't have the complete crash trace, just your photo. I could be wrong.
Seems that one of your CPU core is dying or doesn't wake up fast enough (power issue? heat?). Or a physical device mess with your computer IRQ queue.
https://github.com/torvalds/linux/blob/8689f4f2ea561dd080118eeb05c0255ac9542905/kernel/workqueue.c#L5310 instruction: raw_spin_lock_irq
Try firstly disconnecting every external device. If the crash continue, you maybe can disable CPU cores until you find out the broken one, or disable PF_WQ_WORKER somehow.
The OS splits memory into pages and assigns the pages to applications. A page fault usually means one of two things:
- hardware fault
- programming error
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.
