Kernel panic on LTS after installing Deepin

Hi,

Today i've installed Deepin on my computer, but after a reboot, the LTS kernel get "kernel panic" errors. The non-LTS kernel work great though.
Here is two things that is see during the boot:

kernel tried to request NX-protected page - exploit attempt?
BUG: unable to handle kernel paging request at ffffffffc030c000

The oops message is:

Oops: 0011 [#3] SMP PTI

and the kernel panic one is:

Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009

Let me know if you need more log to undestand what really happen.
Apparently my LTS kernel try to access protected page, but why?

Thank to anyone capable of helping me on this!

Re: Kernel panic on LTS after installing Deepin

I'm guessing this is the same laptop where you have the nvidia/bumblebee issue ?

Brand and model of the laptop ?
post lspci -k output , /var/log/pacman/pacman.log and a full journal from a failing boot.

These logs can be large, use a pastebin client
For filtering jourral output, see https://wiki.archlinux.org/index.php/Sy … ing_output

Re: Kernel panic on LTS after installing Deepin

The laptop is a Defiance V 16.1" from PCSpecialist, also know as a Clevo P960RN

Here are the asked log and output:
lspci: https://pastebin.com/dCqvhUeB
pacman.log: https://pastebin.com/mzAnEqRW (the error occur the 5 jun 2019 on a reboot after the installation of deepin environment)
journal log: https://pastebin.com/Mru27uYn (at first sight, it seems to only show succeeded linux boot and not the panic linux-lts ones)

Thank you very much for taking the time to help me!

Re: Kernel panic on LTS after installing Deepin

OK, I think something is broken between LTS kernel and deepin-anything dkms.
I completely uninstalled deepin from my laptop, run mkinitcpio -p linux-lts, reboot and it run like a charm.
I've also experienced issues with screensaver enabling while gaming and freezing the system with deepin.

Should I point this issue to deepin dev?

Re: Kernel panic on LTS after installing Deepin

It's to early to report anything to deepin devs.

the pacman log shows weird things, like adding --config /etc/pacman.conf .
That's default setting on archlinux, i've only seen it used for very special cases.

[2019-06-02 19:18] [PACMAN] Running 'pacman -S --config /etc/pacman.conf -- community/texmaker'

[2019-06-02 19:21] [PACMAN] Running 'pacman -S -y -y -u --config /etc/pacman.conf --'

[2019-06-05 21:09] [PACMAN] Running 'pacman -S --config /etc/pacman.conf -- community/deepin-terminal'

[2019-06-05 21:04] [PACMAN] Running 'pacman -U --noconfirm --config /etc/pacman.conf -- /home/gaetan/.cache/yay/spotify/spotify-1:1.1.5.153-1-x86_64.pkg.tar.xz'

Are you using some tool (possibly an aur helper) to maintain your repo packages / your entire system ?

Re: Kernel panic on LTS after installing Deepin

Yes, I use yay to manage my package:
https://github.com/Jguer/yay
Also, the freeze issue don't seem to be caused by deepin. I'll work on this later.

Re: Kernel panic on LTS after installing Deepin

I don't think yay is responsible for the issue, but I strongly recommend to use yay (and any other aur helper) only for AUR packages.
Pacman is the archlinux package manager and our whole infrastructure / repo setup expects it will be used.

The logs show several things that may be issues and I think you should consider what you want to do first :
investigate deepin installation further or solve issues.

If the latter, put this on hold and start a new thread . a quick check of the log shows these issues (there may be more) :

- you're using several kernel parameters, are you sure they're all needed ?

-

juin 06 17:48:29 LAPT-ARCH-GNDE kernel: pci 0000:01:00.0: can't claim BAR 6 [mem 0xfff80000-0xffffffff pref]: no compatible bridge window

This kind of error usually points to low-level problems.

- you haven't updated your syslog-ng configuration file since syslog-ng last update.
(most of he time that's a minor issue, but stills needs to be taken care of)
