Public bug reported: My laptop (Ollee L116HTN6SPW) has a Realtek 8821CE WiFi card. Now at hirsute, this is "supported" in the linux-image-5.11.0-16-generic kernel, and it works "well" for both WiFi and Bluetooth. However, this module (driver) causes frequent freezes, randomly but usually within a few minutes of running (thus very soon after boot): screen display remains frozen, no response to either keyboard or mouse input. All I can do is to hold the power button to power off, then reboot.
After reboot, I do not see any crash reports, nor logs about the freeze. Please let me know if I should try to collect some info, and how. For now I use the DKMS module/driver from https://github.com/tomaspinho/rtl8821ce (having blacklisted rtw88_8821ce), and it seems to work perfectly.
