[SOLVED] system freeze

x4rch_q7 · 2024-06-23 06:47:26

I have tried different kernel parameters and neither of them worked.
It's not only in arch but with other distros too fedora, tumbleweed, ubuntu, even. but i have used linux mint with kernel 5.10.. that worked fine.

In arch, kernel version 6.0 fixed the issue for me, but later when i got back from windows, kernel was updated to newer versions and also the issue was there. Then, I used to search for any kernels with version 6.0 and install it, would work for me just fine.

During freeze, the screen gets frozen completely, if audio is playing , the last part of it would just loop , the keyboard also do not work, no caps lock no num lock. I can only force shut down using power button.
I can't even go to tty, nor sysrq works , nothing.

i can use my laptop normally if i disconnect and instead use ethernet or usb tethering. but with WIFI the freeze is guaranteed to occur if i open any heavier apps like browser, etc.

i think this was on my tty, when it froze during arch installation
rtw_8821ce failed to dequeue 4026 skb TX queue 1, BD=0xffffffff, rp -> 4095

This is what journaltcl -b -1 gives;

Freeze happened at around 11:57 , i cannot find any log when freeze happened but everything before or after it , is seemed to be in journalctl..

update:
solution..
create a 'rtw_core.conf' file inside /etc/modprobe.d/
' rtw_core.conf' should have

 options rtw_core disable_lps_deep=1

if this does not solve the issue,
You can add another file 'rtw_pci.conf' with

 
options rtw_pci disable_msi=1
options rtw_pci disable_aspm=1

sounds like a kernel panic, and that's not gonna show up in any journal
=> https://wiki.archlinux.org/title/Kdump but please also post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

to illustrate the system - maybe one of the usual suspects shows up…

Edit:

later when i got back from windows

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

Setting up kdump is such a hassle, somehow set kdumpst but did not find any logs, maybe because i had to force shut down using power button or maybe i made mistakes while setting up.

but please also post your complete system journal for the boot:
sudo journalctl -b | curl -F 'file=@-' 0x0.st

For sudo journalctl -b -1

I am not dual booting. I meant i used windows for some time and came back to arch linux..

kdump should prevent your from having to use the power button by catching the panicing kernel .

The only thing in the journal that looks like trouble is rtw_8821ce what fits your description.
https://github.com/tomaspinho/rtl8821ce/pull/334 - but that's supposed to be fixed since october
Wild guess, try to disable https://wiki.archlinux.org/title/Networ … domization or don't use NM at all (but eg. wifi-menu) to prevent the background scanning entirely.

i managed to somehow enable panic-reboot yesterday, but turns out it gets triggered even without getting to my sddm login, wasted my whole morning thinking my sddm or xorg broke. well here are logs, if these help:

sudo journalctl -b -1 : http://0x0.st/XAR9.txt

sudo journalctl -b : http://0x0.st/XARL.txt

There's unfortunately no kernel message preserved

Going from the context
1. https://bbs.archlinux.org/viewtopic.php?id=296699
2. I see neither pulseaudio nor pipewire in that jorunal?

pacman -Qs 'pulse|wire'

x4rch_q7 · 2024-06-27 05:20:51

created and enabled panic-reboot.service with this configuration :

[Unit]
Description=Reboot on kernel panic

[Service]
Type=oneshot
ExecStart=/bin/sh -c '/bin/dmesg > /var/log/dmesg.log; /usr/bin/logger "Kernel panic - automatic reboot initiated"; /usr/bin/sleep 5; /sbin/reboot'
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

and i tried to trigger the freeze, it occured but it didn't reboot just the system freeze with audio loop, no input working .only force shutdown works.
journalctl -b -1 : http://0x0.st/XmSq.txt

but then booting into os gave continuos reboot until i diabled the panic-reboot.service from arch chroot.

2. I see neither pulseaudio nor pipewire in that jorunal?
pacman -Qs 'pulse|wire'

pulseaudio is already installed and working, 'user-level service' or something i dont know, but sound is working fine

The symptoms describe a kernel halt, you're not gonna write something to disk or run userspace commands at this point.
If anything works it'll be https://wiki.archlinux.org/title/Keyboa … el_(SysRq)
Otherwise you've to setup https://wiki.archlinux.org/title/Kdump to catch the kernel.

Have you already tried https://aur.archlinux.org/packages/rtl8821ce-dkms-git ?

x4rch_q7 · 2024-06-29 05:21:55

sadly no, I tried sysRq keys on normal environment and on tty ,both works fine except during the freeze.
I even tried doing that from openSSH but the terminal on other device becomes unrespomsive until i close the connection.

Have you already tried https://aur.archlinux.org/packages/rtl8821ce-dkms-gitto ?

Yeah, this was the first thing i tried.

Here is a dmesg i found, was not during the freeze but thought might be useful
https://0x0.st/Xmgw.txt

Otherwise you've to setup https://wiki.archlinux.org/title/Kdump to catch the kernel.

kdumpst didn.t work so, going to try the manual method. Compiling on my device will be hassle, sigh.

seth · 2024-06-29 22:16:58

You don't have to compile anything, the arch kernels have the relevant configs enabled.

seth · 2024-06-29 22:23:30

That's just an out-of-context warning concerning rtw_power_mode_change.
Ading "rtw88_core.disable_lps_deep=Y" to the kernel parameters might help with that - no idea whether it's related to your freezes,

adding this didn't help.

if i keep my device idle for 1 hr+ without using apps and then use it, the probability of freeze is very less. and those warning pos up sometime in journalctl..

I am trying to set up kdump, but i am stuck at this

Next you need to tell Kexec that you want to use your kdump kernel. Specify your kernel, initramfs file, root device and other parameters if needed:
 # kexec -p [/boot/vmlinuz-linux-kdump] --initrd=[/boot/initramfs-linux-kdump.img] --append="root=[root-device] irqpoll nr_cpus=1 reset_devices"

sorry for this newb question, but how do i get or create the vmlinuz-linux-kdump or initramfs-linux-kdump.img ??
https://wiki.archlinux.org/title/Kdump This wiki is very overwhelming for the newbie arch users like me.
i also searched to find easier tutorial but found none .
Can this issue be caused by skipping a bios update??

Nevermind, kdump is just a notation, current kernel can be used

After doing some testing and breaking, i managed to diagnose and fix the issue. As mentioned in #11 the issue was indeed with the rtw_power_mode_change but instead of adding "rtw88_core.disable_lps_deep=Y" to the kernel Parameter the solution which worked is to create a 'rtw_core.conf' file inside /etc/modprobe.d/
' rtw_core.conf' should have

 options rtw_core disable_lps_deep=1

if this do not solve the issue,
You can also add another 'rtw_pci.conf' file with

 
options rtw_pci disable_msi=1
options rtw_pci disable_aspm=1

This thread can be marked as 'Solved'. Thankyou

seth · 2024-08-06 15:53:24

???

modinfo rtw_core rtw_pci
lsmod | grep rtw
systool -vm rtw_core
systool -vm rtw88_core

Mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
