faulty realtek wifi driver freezes computer rtw88_8821ce

[technik007_cz]

I bought few Geobooks 1E  and all had regardless distro same issue. Random hangups immediately or few minutes after boot finished or after few days of run or hours.

 

On Armbian distro after trying some other things I enabled kernel messages in sysctl.conf. And then I got something like, luckily immediately when login prompt appeared, :

rtw_8821ce 0000:01:00.0: failed to dequeue 4088 skb Tx queue 5, .... when laptop stopped responding to keyboard immediately afterwards.

 

After some research I found solution, plugged USB lan adapter, disabled wifi otherwise it would knocked system down a did these next steps to replace wifi driver and hopefully after reboot 4 of these laptops this driver seems to work better without hangups.

 

nano /etc/modprobe.d/rtw88_8821ce.conf && update-initramfs -k all -u

ADD NEXT LINES INTO OPENED FILE =>

blacklist rtw88_8821ce
options rtw88_core disable_lps_deep=y 
options rtw88_pci disable_msi=y disable_aspm=y

 

 

NEXT COMMANDS:
sudo apt update && sudo apt install bc module-assistant build-essential dkms git -y
cd /usr/src && git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo m-a prepare
sudo ./dkms-install.sh
sudo nano /etc/modprobe.d/rtw88_8821ce.conf
blacklist rtw88_8821ce

 

note: it should work without "options" lines which I found elsewhere as solution to resolve this problem without driver update
