Help diagnosing a kernel panic

AZMCode · 2024-08-11 21:02:13

Hello!
I've been trying to figure out why, after a while, my laptop running Arch just crashes with a kernel panic.
I've already got kdumpst using kdump, though I'm not making the full memory dump.

The following messages in dmesg are recovered after the panic:

This is my first time dealing with a recurring kernel panic, so I came here for some advice.
Any idea how I could narrow down whether it's the kernel itself, or a specific kernel module, and how to find it?

gromit · 2024-08-12 07:28:28

Does this kernel panic also happen with an untainted kernel (i.e. with the virtualbox modules removed)?

Also does it occur on the latest mainline release candidate aswell?

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.11rc3-1-x86_64.pkg.tar.zst

Can you solve the problem by downgrading? Which is the first version that does not show the problem?

Will come back to you on that. If the issue is resolved after these steps I'll post too.

I have done both of those, and it took a while, but I did get another kernel crash

I'm guessing more information is needed to figure this out, but I got the time and patience to provide that information and learn a thing or two. How to proceed here?

Could you please remove the virtualbox stuff for now so we can test this on an untainted kernel?

AZMCode · 2024-08-14 02:05:04

I thought I did. I uninstalled the virtualbox kernel modules package before the second crash log was generated. I guess I haven't done so correctly then. How would I go about doing this?

ap_qld · 2024-08-14 02:59:44

If you have Nvidia hardware, this thread maybe relevant: https://bbs.archlinux.org/viewtopic.php?id=293400

gromit · 2024-08-14 07:15:14

What did you remove? And whats the output of "dkms status"?

AZMCode · 2024-08-14 18:58:22

I uninstalled `virtualbox-host-modules-arch`, and `dkms status` returns command not found, and I currently don't have `dkms` installed either

With respect to the GPU hardware, here's my fastfetch output with irrelevant details stripped

I'm supposed to have 12GBs of ram (one 4GB stick and one 8GB one) but I went a bit overboard with kdumpst due to its inability to open my encrypted root partition so I just went and gave it 2GB so it wouldn't complain. Doubt that's part of the issue though.

I run intel integrated graphics, so I doubt it's an NVIDIA issue

Do you also have a crash that's not tainted "G" ("W" is ok)?

Says Not Tainted, if I checked correctly

AZMCode · 2024-08-14 23:58:04

I've noticed they're all page faults. Does this indicate my memory may be at issue here?
I did just get it replaced after a POST code told me my memory was bust, though I kept one of the two original sticks (crashes have happened with both original sticks, each tested separately with a new 8GB stick, which just confuses me)

I doubt both memory sticks died at the same time, so maybe the motherboard?

There's also the chance it really is a software bug, which is why I'm here.

seth · 2024-08-15 07:24:29

Does this (only) happen under RAM pressure?

I did just get it replaced after a POST code told me my memory was bust

Were the crashes before or after (or both) the replacement?
Did you replace them yourself or had them replaced by some pro or by some "bro who's really good with computers and such"?
(They might not be properly seated)

Can you downclock the RAM in the UEFI/BIOS settings (choose the most conservative timings, clocks, …)?
=> memtest86+, run it at least over night

AZMCode · 2024-08-16 01:57:11

I got the RAM replaced by a professional, they're properly seated. The crashes happened before and after.
I have also run a memtest before and after the replacement and it all CHECKed out. I'll try running it overnight.

I have never down over/underclocking is it safe?

seth · 2024-08-16 08:06:57

It's not a real "underclock", you just select the most conservative settings and that's considered to be beyond safe - it's typically *required* for heterogenous DIMMs (different brand or even just batch)

AZMCode · 2024-08-16 12:19:20

Have run the memtest overnight, and it's the memory
Got multiple failures

Should I try to underclock it, or remove the old memory stick first?

seth · 2024-08-16 12:48:23

That's really up to you, do NOT underVOLT the RAM, you just want to use the most conservative settings (and eg. certainly not anything like XMP) and if you've currently and old and a new (ie. heterogenous setup) DIMM, that's kinda mandatory anyway. Full speed can typically only be achieved for equal DIMMs, same vendor, same brand, usually same batch (ie. they came in the same box and the serial numbers are nnnn and nnnn+1)

AZMCode · 2024-08-16 18:26:28

Will do. In any case, the tip of leaving the memcheck overnight gave me a way to conclusively test if what i'm doing is OK or not. I'll make sure to underclock the ram if it keeps happening, and test again. I appreciate the advice. I'll check back in eventually if I manage to fix my issues, or have any further problems. Thanks for your patience.

AZMCode · 2024-08-16 20:33:55

Oh God it gets even worse. I have tried both old sticks, as well as the new stick by itself, and I'm still getting memtest FAILures.

I'm going to try updating the BIOS and if that dont work maybe getting a professional to try to suss out the issue. Maybe thermals or such.

Is this still the correct forum to ask for advice about this?

seth · 2024-08-16 20:35:36

It's not the most specific platform and we're not going to be able to systematically help you but I'd test the DIMMs in some other board.
