[SOLVED] System crash: Kernel panic invalid opcode 0000 PREMPT SMP PTI

Context (maybe relevant)

  • Have been using arch on my laptop for 2 years without facing major issues

  • Laptop recently failed to start at times, crashed frequently and the charging light would not come on sometimes

  • Technicians said that the Power IC had shorted and replaced/repaired it

  • Problem went away but Arch did not boot and the laptop always entered the BIOS menu

  • I used a bootable usb to reinstall arch. However, I found that my partitions and data were intact and I just used the same partitioning without formatting

  • I reinstalled GRUB and got my system back to exactly how it was. So, probably the bootloader files went corrupt due to extensive hard booting

Problem

  • A new problem has emerged, where the kernel panics and the system hangs

  • I have to hard reboot every time, and the panic messages are not persisted. Hence, the snapshot below

  • The first time I use the laptop everyday, there are no crashes for a long time (5-10 hours)

  • After the first crash, subsequent sessions crash within the first 10 minutes

  • This strongly suggests a hardware problem, more like a heating problem. But I monitored the CPU temperature, which was fine throughout (~53C) and the laptop didn't seem unusually hot either

  • At this stage, I am clueless. Is it actually a hardware problem? If so, how do I narrow down to the faulty component?

Let me know if I need to post any other details. I have never dealt with kernel panic or hardware faults before. Any help is greatly appreciated.

Update: Faulty GPU. See comment below.

Re: [SOLVED] System crash: Kernel panic invalid opcode 0000 PREMPT SMP PTI

Ensure your microcode is set up and generally update your system. You might also want to disable laptop-mode-tools to ensure it isn't triggering some faulty power saving option.

You will likely also want to test your RAM for a day or so

Re: [SOLVED] System crash: Kernel panic invalid opcode 0000 PREMPT SMP PTI

The scenario sounds as if maybe the case warms up, deforms, causes tension and boom: you got a loose connection.
You could try if you can restore the 5-10h uptime capacity by aggressively cooling it down, eg. putting it in the fridge for some time™ (where you keep the butter, NOT where you keep the ice cream. And power it off before doing so, esp. if you've a spinning HDD)

Edit: and make sure the humidity in the fridge isn't too high (ie. if everything has drops of water on it, you should defrost it before putting electronics there)

Re: [SOLVED] System crash: Kernel panic invalid opcode 0000 PREMPT SMP PTI

Thank you for your support. I tried everything you guys suggested but without much luck. But, I kind of managed to fix the problem anyway.

  • Laptop soon went back to the initial state where it won't boot for a long time

  • Booted without SSD, HDD, battery, etc (one at a time) but the problem persisted

  • Screen distortions showed up at times and the screen sometimes went completely green

  • Finally uninstalled/blacklisted GPU drivers, and that worked like a charm

My diagnosis is that I have a faulty GPU but it starts misbehaving only when it heats up. The GPU is built into the motherboard, and I'd rather get a new laptop than replace the motherboard. Till then I'll be using a GPU less laptop which, sadly, defeats the purpose of me going with MSI in the first place. I wonder if I should consider using the GPU at times till it heats up without damaging anything else. Probably not. Marking this SOLVED.
