I’ve been using Manjaro for some time with no issues. I recently bought a new PC and found out my wireless card was not supported. I managed to install the driver in kernel 5.10 with the help of, at first, the driver provided by Tomás Pinho, and later with RTL8821CE-dkms from AUR.
When I upgraded the kernel to a version above 5.10 I noticed that there was a wireless driver that worked out of the box, but it causes my system to randomly freeze from time to time. The system freezes completely, keyboard included.
As of now, I can only use wi-fi with no issues in kernel 5.10. I tried to check the logs to see if I could find the problem or at least a hint of what makes my system freeze but I didn’t find anything (I may lack some knowledge in bug tracking).
I am not really asking for help per se, because I decided to use kernel 5.10 for now, but since it is a major issue I would ask the Devs to check this out. There may be other people with this same issue (although I searched the forums but found no issue similar to mine).
If I can be of further assistance please ask.
Thank you and keep up the good work.

Issue persists on both Manjaro XFCE and GNOME
Especially the Linux has multiple kernels section, then stay on 5.10 but now you know why you should.
If you insist on getting a developer to look at it, please read the section What’s this Upstream / Downstream business? in the same tutorial and then file a bug upstream
Please note that:
Compared with other Free/Libre & Open Source Software it’s hard to report issues to the Linux kernel developers: the length and complexity of this document and the implications between the lines illustrate that. But that’s how it is for now. The main author of this text hopes documenting the state of the art will lay some groundwork to improve the situation over time.
