I have sent the patch to upstream: https://lore.kernel.org/linux-wireless/20210607012254.6306-1-pks...@realtek.com/T/#u I add your description of this bug in the commit message. If there is anything wrong, please let me know.
About the warnings "timed out to flush queue 2", my colleague told me he cannot see the symptom. It seems like you don't need special steps to reproduce it, right? If you have, please tell me the steps. Thank you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1927808 Title: rtw88_8821ce causes freeze Status in linux package in Ubuntu: Confirmed Bug description: 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.
