[SOLVED] System randomly crashing and then rebooting

c_danil0o · 2021-03-25 14:48:33

I've already tried downgrading kernel to the version I was using, but that didn't help. Only thing I could remember that I did before the issues started appearing, was installing plymouth, but I don't see how that could affect the system. Also I completely removed it to see if it was causing system crashes, but the crashes continued appearing. I don't remember changing any drivers.
Recently I tried booting live Manjaro usb and same crashes happened there few times.

It's either a hardware issue (you have to run memtest86+ for MANY cycles to be sure about the RAM integrity) ie. CPU, RAM, PSU (any loose contact) or comes from the ACPI (UEFI update?)
The kernel should™ not just perform a hard reboot and since you tested various versions and other distros, it's incredibly unlikely the software stack.

I agree with you on that.

I've run memtest86+ for 8 cycles and it showed that ram was in perfect state.

I did have an issue when I accidentaly changed boot mode in BIOS from "UEFI only" to "Legacy support" which deleted my UEFi configuration when I reverted it back to 'UEFI only' and I had to manually configure it again from Windows with bcdedit (added 'refind') and checking that everything works with efibootmgr, when I was able to boot Arch. Could that somehow affect the system?

Sure. The more important question: does this incident fall into the period where this problem started to show up?
Ie. did you ever get those random reboots before and how long after the UEFI incident until the problem appeared?

c_danil0o · 2021-03-25 15:38:38

If I am remembering correctly, UEFI incident happened few days before the hard reboot issues.
What do you recommend doing? Do you think formatting EFI and Arch partitions, installing Arch again and switching go Grub bootloader would be a good idea?

seth · 2021-03-26 08:12:54

Formatting the EFI will require some fix for windows as well, so be prepared for that.
The grub loader should be less of an issue, but I could imagine that something got messed up in the ACPI table and some reboot entry lingers around there.
Is there any kind of pattern for the reboot (in relation to either the startup/reboot time or wall clock)?

A CMOS reset might help you.

Hi, it's me again, back with the same problem. In short, I have issues with linux hard rebooting totally random, without showing that anything is wrong. I can't even capture something in logs. Screen just goes black, and laptop starts booting again. Crashes sometimes happen everyday for a few times, but sometimes they don't show up for a few weeks. There's not any pattern in theirs appearance. I tried everything to fix this issue and struggled for few months, but nothing helped. Only thing left was to completely format my drives and reset everything, which I did yesterday, but after trying to install arch distro (in this case I tried Manjaro), system crashed in the live environment exactly the same way, as it was crashing before.

You can see more details from my posts in this topic.

Is there anything else you can think of that could cause these issues, or my laptop somehow has suddenly became uncappable of running linux ?
Could Xorg display server somehow cause this crash? Switching to wayland is the only thing I haven't tried, but I cannot see how this could be the problem.

Thanks in advance.

Have you tried another (more wattage) power source and/or battery (if possible) ? Also display adapter might use shared memory with cpu, and depending what you're doing, there might surprisingly low memory available, so adding more RAM could help. Hard drive failure is also one possibility, random reboots can be the first symptoms of that too.

I am using original 63watt charger, and haven't noticed it getting warm(sign of lacking power). Battery is also decent(6-7 hours of SOT), and I don't think it is causing this problem.
Laptop has 4gb of ram, and I did memtests which showed that ram is OK. If it was low memory issue, I think there would be some kind of error report showing in logs.
I agree with you that hdd could be the issue( i actually use m2 ssd), but I also run drive health and s.m.a.r.t checks and everything seems ok.

I guess since you're using ssd and tests show ok, hdd is not a problem. For traditional hdd those s.m.a.r.t. etc checks don't necessarily tell all the truth. I've read somewhere that some ssd might run very hot. Perhaps someone has expererience how temperature sensitive ssds are.

Hi, just wanted to let all the others which may be facing this issue, to know, that I managed to solve it by updating BIOS to latest version for this model. My mistake was that I thought I was already on latest BIOS. Big thanks to everyone who tried to help me. Cheers!
