I experienced the bug on my Lenovo IdeaPad L340-17IWL with Ubuntu 20.04 up to
date and a Realtech rtw_8821ce.
I spend hours to try to find a setting, practicing the Computer Assisted Waste
of Time.
I bought an external wifi dongle with another Realtech 81... chip (I've not it
at hand now) and
The above is sadly false, a bit better, wifi lasts a bit longer but
still fails after a while.

I've attached full dmesg and lspci -vvnn
The bug seems to manifest when the laptop is on battery power. I've made
several boot cycles this evening with kernel 5.10 rc2. When the laptop is

Hi, Feng
Unfortunately, in my case, wifi crashes each time (at a random period of time
from boot) with kernel 5.10 rc1 and rc2 and disable_aspm removed.
The good thing is that I can use the disable_aspm workaround which makes wifi
stable.
I attached the error parts from dmesg.

campus, does it work but flaky? Then it sounds like a different bug.
Can you please attach dmesg under v5.10?

Hi, I booted by disabling secure boot as suggested and it seems to fix

After disabling secure boot, I had to reboot into Windows once to get
