The first message, "rtw_8821ce 0000:04:00.0: timed out to flush queue
2", means the buffered data isn't transmitted properly. I think this
isn't a big deal.


The second message, "rtw_8821ce 0000:04:00.0: firmware failed to leave lps 
state", means firmware doesn't respond the request of leaving LPS. The reason 
may be firmware is too busy at that moment, but it can work well, no? An 
alternative way is to use 'iw [dev] set power_save off' to turn off this 
function.


I plan to add a quirk to make someone who uses the same laptop can use Linux 
smoothly. 
Could you provide your manufacturer and product names by below command?
  sudo dmidecode | grep "\(Manufacturer\|Product\)"
With these information, I can provide a patch or a driver tarball to check ASPM 
issue again.

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.
