Enabling Wi-Fi (Realtek RTL8821AE) on ASUS X441URK will lag & freeze the screen, use more than 90% of CPU for /usr/lib/systemd/systemd-journald, PCIe Bus Error on restart & shut down

I recently discovered that only when I enable Wi-Fi, htop shows an abnormal CPU usage of more than 90% for /usr/lib/systemd/systemd-journald, which then leads to a bunch of problems.
I guess it's logging multiple errors in the background, maybe the PCIe Bus Error?

Anyways, I then disabled Wi-Fi & enabled Airplane mode. When I restarted my laptop, I was bombarded with multiple PCIe Bus Error for three seconds on the screen, then proceeds to restart.
After restarting my laptop & booted on my desktop (Wi-Fi is still disabled & Airplane mode enabled), I checked htop and the CPU usage this time was normal or mostly at 0.7% - 2%.
I restarted one more time and there were no PCIe Bus Error if Wi-Fi is disabled. Restarting was smooth & normal.
There is indeed something wrong with the Wi-Fi, specifically the Wi-Fi driver.

By the way, this issue doesn't occur on a Wired connection or when I use USB tethering from phone to laptop. The Wi-Fi driver in question and responsible for this headache is the RTL8821AE.

I've had this issue since 2017, made me pause using Linux for five years and I've been blaming it all on Nvidia. :face_with_hand_over_mouth:

I searched on Google & the Garuda forum for similar or related issues for the rtl8821ae driver and I found some. Although I haven't attempted any of the fixes yet because I want to verify here first with you, the experts, for my particular case and because I don't know what I'm doing. I still need help.

  1. Unable to install Mint due to PCIe bus error [SOLVED] - Linux Mint Forums
    Nov 23, 2019

    • A user from Linux Mint had a similar encounter with PCIe Bus Error, their solution was to remove the kernel module or driver for rtl8821ae and adding the pci=nomsi kernel parameter to GRUB.

  4. RTL8821CE WiFi adapter - Screen freezes when connecting to wifi
    Aug 1, 2021

    • A fellow Garuda Linux user had a similar issue with rtl8821ae, but on rtl8821ce instead. Installed an alternative Wi-Fi driver (rtl8821ce-dkms-git) from AUR, blacklisted the default Wi-Fi driver with a created blacklist.conf file that's stored at /etc/modprobe.d/, then added a pci=noaer kernel parameter to GRUB and set band to 2.4GHz.

My thoughts, questions & concerns

  • I'm thinking that removing the Wi-Fi driver or kernel module of rtl8821ae completely might reduce the internet speed significantly or there might be no internet connection at all.
  • I know a little bit about the common kernel parameters for GRUB like pci=noaer, pci=nomsi & pci=nommconf, but preferably I really want to make these the last or second to the last options. It just feels like I'm burying the problem or I'm disabling something systemwide which who knows, my system might need them too. But I'm also not against using them if I have no choice.
  • Someone said in this comment that the RTL8821AE and the RTL8821CE, uses the same driver (rtl8821ce-dkms). Is this true? Or can rtl8821ae use that driver? If it can, I might be able to follow the guide in number 4.
  • Does rtl8821ae have any alternative driver at all?
  • Are there any repository & list of versions to downgrade for rtl8821ae driver? Since the driver is baked to the kernel from version 3 & newer.
  • What else can I do to solve this problem?
  • If somebody else has another solution, please let me know. I'm really excited to keep using Linux with this gorgeous distro.

First I can't help you with that since I don't have the knowledge about the issue.

I just wanted to tell you, you did a very well post for your issue in the forum which (sadly) rarely appears. I'm sure there will be someone with deep insight into the issue who will help you out.
We've some great ppl here.

All the best with your issue, I'm sure it can be solved,

Bruce :shark:

Although I cannot consider myself a networking expert and am unable to provide you with a solution, I will give you some general advice:

  • If you disable the kernel module of rtl8821ae, the wifi will not work. so this option only applies if you can use an ethernet connection or an external wifi dongle.
  • For point 4, I really believe this is not true. by the way, the upstream site of the package (available in Chaotic-AUR) that includes the realtek proprietary drivers clearly states that it does not apply to RTL8821AE.
  • On an initial search, I have not found alternative drivers, either via threads in the forum or in the AUR :frowning:
  • I would not dislike trying the kernel boot parameter pci=nomsi, at the very least, if you notice improvements, keep the system under control for a while.
  • First of all however, I would try some other kernel, at least linux-lts

I see, I will have to greatly consider these two suggestions. Thanks, I now know what to do. Though I'm still hoping for someone to bring the good news and I might do some trial & error myself.

Try running these commands:

sudo systemctl stop NetworkManager; sudo modprobe -rv rtl8821ae; sleep 3; sudo modprobe -v rtl8821ae  msi=1; sudo systemctl start NetworkManager
sudo systemctl stop NetworkManager; sudo modprobe -rv rtl8821ae; sleep 3; sudo modprobe rtl8821ae msi=0 msix=0; sudo systemctl start NetworkManager
sudo systemctl stop NetworkManager; sudo modprobe -rv rtl8821ae; sleep 3; sudo modprobe -v rtl8821ae swenc=1 ips=0 fwlps=0; sudo systemctl start NetworkManager

Check after running each of the commands for improvement.

Post all inputs and outputs please.

Is your BIOS up to date?

Doing it right now

I think it is. Last time I contacted asus support was on 2017 they said it was up to date, then when I updated Windows last month, it came with the bios/uefi update.

Do I have to reboot after running each command?

Do not reboot.

Be sure all Windows advanced wifi power saving options are disabled in the Device Manager.

It's after 3 am here, I'm going to get some Z's. :zzz:

Perhaps stupid question :wink:: shouldn't it be rtl8821ae instead of rtl8723ae in those command sequences?
Furthermore, I think the system should be monitored after each of the 3 commands (3 different tests). Maybe this was done. Just in case, for clarity...

I just wanted to point out that your screenshot does not illustrate that this has been accomplished (doesn't mean it hasn't been, just that it can't be seen).

In that second screenshot you have to click where it says "Change advanced power settings", then click "Change settings that are currently unavailable". Uncheck "Turn on fast startup" and change to shut down when you ask to shut down (which is not the default behavior).

If you do not change this setting, Windows will hold on to certain system resources when it is supposedly shut down, including famously the network card which can break WiFi in Linux.

You are absolutely correct.

My bad, it was very late in the morning when I posted those commands and I got my wires crossed on the adapter driver in use. I will edit the commands to make sure they are what the user needs to run for their adapter.

Yes, each test should be run separately to determine if it has a beneficial effect, (with no reboot after executing the command).

I wasn't 100% sure because with that Realtek stuff you never know...
And I was in a more favorable time zone :wink:

At the second screenshot, that's the advanced settings for changing the power plan settings.
You're referring to the settings for choosing what the power buttons do. I've already done those necessary steps before dual-booting as instructed here, except for changing power button behavior to shut down. Now I changed it & I'll also take note of that one.

I thought the same thing but I also thought that maybe we were trying some different but compatible driver that's also included in the kernel. :smile:

I did, they had similar CPU readings with the screenshot.
I will redo it with the updated commands.

First command had a high CPU usage, htop showed around 90%-100%+

Second command, CPU% at around 60%-80%

Third command, CPU% went up to around 97%-100%+

Actually, I did them twice in a row, from first to the third command and repeat again to notice some changes.
CPU usage stays 50% & above with the three commands, the second attempt may have lowered the CPU usage of some commands that were higher on the first attempt so I wouldn't base any changes with just the random +/-30% up & down changes.

What changes do I exactly need to take note of here?
Also, I recently updated my system. I'll update my garuda-inxi & lspci -k on my post.

I can't edit it anymore so I'll put them here:

Are you sure their are not other system/firmware BIOS updates now? 2018 was a long, long time ago in cat years.

I contacted ASUS support just now to double-check, gonna wait for their reply. But I've always been under the impression that they never really cared about my particular device. We'll see.
