[SOLVED] Repeated kernel problems/freezes since 6.7.6

Dual-booting Arch with W11 on a fairly new Lenovo LOQ 15IRH8. Recently added a second SSD and moved my Arch install over with rsync (my media folder is still mounted on the original drive), no apparent problems. Changed mkinitcpio at the same time to use systemd initramfs, lz4 compression, and only six hooks (systemd autodetect modconf block filesystems fsck); I also set up hibernate, which I had not had before. I boot from EFISTUB with a UKI.

On the 28th, my laptop froze waking up from S3 sleep after a couple hours - it woke up, but no display or input. Didn't think much of it and did a hard shutdown. Saw nothing relevant in the logs.

On the 1st, laptop froze after being left idle (in S0) for a while. I woke up the screen and it immediately froze, but responded to REISUB. I looked through the logs and found a kernel oops from 45 or so minutes before I tried waking it up, shown at the end of this message.

On the 2nd, laptop froze again after entering "shutdown -r" in terminal. REISUB didn't work and had to do a hard shutdown, nothing in logs.

Today again, laptop froze after "shutdown -r". Kernel had booted on 6.7.7 and I was rebooting after updating it to 6.7.8. This time it displayed a message about a kernel panic - the message does not seem to have been saved in any logs. I read enough of the message to tell that the RIP was different and ended with "systemd exited with irqs disabled", but I didn't look at it carefully.

Someone on Reddit (/r/linuxquestions), with a different Lenovo laptop running Arch, had a very similar kernel panic a couple days ago, which makes me think this is a bug that isn't specific to my install.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I also dual boot with Windows 11,and mounted a ntfs partition automatically.
Maybe it is a ntfs3 driver bug.
Edit: the panic also occurs without the ntfs3 driver.

Same problem. Auto-mounting ntfs from Win10 and Lenovo laptop

kernel: BUG: unable to handle page fault for address: 00000000000029af
kernel: #PF: supervisor read access in kernel mode
kernel: #PF: error_code(0x0000) - not-present page

Nothing after that

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Have you tried bisecting the issue between 6.7.6 and 6.7.7?

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I have the same laptop, I saw that kernel panic only when rebooting twice since 6.7, I would recommend to update your bios and use thermald (that laptop is a small oven)  :

It definitely happens with:
6.7.6.arch1-1
6.7.6.arch1-2
6.7.7.arch1-1

No issues so far on 6.7.8, but it's only been a day and a half, and it apparently took several days before a crash on 6.7.6.arch1-1. I updated to it on the morning of the 23rd. If I find a way to reproduce the bug by force, I'm happy to test it on all recent versions; as it is all I can really do is wait. The only thing all of my freezes have in common are that they all involved some aspect of the system being in a low-power state. Would be interested knowing if that's the case for other people.

My temps are weirdly extremely good (as I type this, 35 for my CPU, 25/31 for my two drives; even running a stress test nothing is ever close to hot, and cooler on Linux than on Windows. I should check DIMM temperatures, given the error, but the Arch wiki's guide on that doesn't work for me. All I know is that they're normal on Windows 11. I'd rather not do a bios update for many reasons, but if this keeps happening and there really is no other explanation, then I guess I will.

For whatever it's worth, I did a full system backup on the afternoon of the 28th (just before the first crash, but after the update to 6.7.6), so if there's any useful information I can look up there, let me know.

Well since I bought that laptop August last year there were 3 bios updates, one fixed a strange behavior of the fans that they were running constantly when the laptop was on igpu mode (config on bios) when the logical thing was to be running when on hybrid/dgpu mode,  only  with the fans running constantly before that bios update I got low temps, normally since then it is on 45C avg. 

Also I changed nvme and wifi card just after I bought it and that error happened even with that. The thing that I see different is the memory that supposedly is quad channel, when checking the speed on Windows (hwinfo) the speed appears as it is calculated as dual channel, but checking on linux the speed appears as divided by 4 like it is running on low speed.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I also dual boot with Windows 11

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Maybe it is a ntfs3 driver bug.

https://wiki.archlinux.org/title/NTFS-3G

I read enough of the message to tell that the RIP was different and ended with "systemd exited with irqs disabled", but I didn't look at it carefully.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I have the same oops on the lts kernel. It only appears randomly on every 2nd or 3rd shutdown and prevents the system from powering off. I will try and go with the numa=off kernel option.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

This doesn't seem to be an Arch-specific bug: found this from someone running 6.7.6 on the OpenSUSE forums. Exact same RIP as myself, @bbaa, and @~tfa. I'm not sure of the procedure now - should it be reported on the main linux kernel bugtracker? (I still have had no issues since going to 6.7.8, but someone else could say otherwise.)

I do notice that it seems like an awful lot of us having this bug are using gaming laptops, which makes me suspect Nvidia even though it doesn't really match the traces. Usually if something fails catastrophically on Arch, I'd wonder about the Nvidia drivers first. Unlike the kernel, which updated five and a half days (for me) before the first crash, I updated to the 550 branch of Nvidia drivers exactly on the 28th, the day of my first crash.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

If this is the numa bug, it's already addressed. So you'd check for that first (esp. if you can somewhat reliably trigger this)

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Hi all,

I was getting similar bugs and I think the issue is related to the nvidia driver. I installed nvidia-open-dkms and it went away for me. I also have numa=off in my kernel command line just in case.

I was able to reproduce the issue using 

stress-ng --class vm --all 1

though sometimes I needed to ctrl+c  and rerun it a couple times before I'd start getting panics. Rebooting would also hang about half the time. I tried numa=off and using an lts kernel; both did not work. Once I switched nvidia drivers to nvidia-open-dkms, I was not able to reproduce the issue, which makes me think that worked.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I hit the bug again today, with numa=off enabled, so I can confirm, it is probably not the root cause.

The system runs stables for hours, with switches between suspend and idle and multiple monitor connects and disconnects and the issue only arises at shutdown or reboot. I am on nvidia 550 as well (nvidia-dkms-tkg). I am also on a Wayland session an a hybrid GPU setup.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

With the recent hiccups in the nvidia blob, you coul also try to revert to the 535xx drivers (dkms + utils) from the https://wiki.archlinux.org/title/Arch_Linux_Archive hmm

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Linux 6.7.9 has just been released, which should bring the fix for this issue.

I can also confirm that I can only reproduce the issue on my old nVidia-equipped system, but not on Intel or amdgpu graphics.

EDIT: instead of using 'numa=off', it might be better to use 'numa_balancing=off'.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Some kdump analysis shows that kernel panic seems to be related to files in /sys/fs/cgroup.
I can confirm that doing a getfattr loop on files in /sys/fs/cgroup after uninstalling the nvidia driver won't cause a panic/oops.

Type "apropos word" to search for commands related to "word"...

With the recent hiccups in the nvidia blob, you coul also try to revert to the 535xx drivers (dkms + utils) from the https://wiki.archlinux.org/title/Arch_Linux_Archive hmm

This is the way to go, yet on 550 I have the best cold suspend behaviour, I ever had with nvidia. Can connect to an external monitor at work and it supends, yet still can run apps on the dGPU.

I will try another thing, since it can be related to control groups and there is always that systemd error at the end, I will disable nvidia-powerd and if that doesnt help, disable nvidia-persitenced as well. The former one enables boosting of the GPU and the latter one keeps vram between context switches as far as I know.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

https://nvidia.custhelp.com/app/answers … ruary-2024

This sure looks like the update that caused problems. Notice the mentions of bugs connected to NULL pointer dereferences in Linux. Looks like Nvidia tried to fix some vulnerabilities and broke a bunch of things instead.

(I did switch to nvidia-open, but if that doesn't fix it I guess I know I can just go back to the 545 version and stay there forever lol. Thankfully I don't game on Linux so up-to-date drivers aren't a must.)

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I too reverted back to 545 and the issue is gone. I did not test my daemon idea, cause after the last update of 550, Unity in a Vulkan context kept crashing upon load. Same for the vulkan-beta drivers.
Guess this thread is solved then, at least the riddle. smile

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

I have the same issue. I firstly think the crash was triggered by file system corruption caused by faulty RAM stick on my laptop.
I have two PC with 550 Nvidia drivers and only the laptop is affected by the issue.

It's a problem with memory allocation on laptops with specifically the 550 branch of Nvidia drivers. The only current fix is rolling back to 545 or earlier (which, at least for me, required using nvidia-dkms). I did try nvidia-open for a bit but it had a different unrelated bug I didn't want to deal with.

I could mark this thread as solved - is that the protocol here? It won't truly be solved until Nvidia fixes the bug in a future driver update.

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Basically yes, you found an answer and even if that answer is a "downgrade and wait for nvidia to fix their shit" workaround, there's nothing left to do in this context and others researching the same problem will benefit (so it helps them if the thread shows up as [SOLVED] in google)

Re: [SOLVED] Repeated kernel problems/freezes since 6.7.6

Update, for anyone affected by this:
If you feel adventurous to try the latest nvidia driver again, the problem is increasingly likely the nvidia_uvm module.
This is mostly relevant for cuda and to use the GPU in containers, but also for https://wiki.archlinux.org/title/NVIDIA … with_NVENC and eg. utilized by gimp for HW acceleration.

If you critically rely on that, this isn't a viable solution but it would still be awesome if you can confirm the condition.
Afaict the module also comes w/ a ton of paramters, so if you've it around, posting

modinfo nvidia_uvm

might shed further light.

https://wiki.archlinux.org/title/Kernel … and_line_2

module_blacklist=nvidia_uvm

And if anyone here happens to post at https://forums.developer.nvidia.com/t/s … /284772/27 you might want to forward this.
Particularily if you could confirm it.
