Hi, Feng
Tested and the error still appears. I'm starting to think it has something to
do with my laptop in particular. Dmesg attached.

Hi, Feng
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
plugged in the network works fine. when the laptop is on battery power wifi
crashes.

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.

Unfortunately, kernel 5.10 rc1 doesn't fix the bug for me (Lenovo Y530-15ICH
with bios version 8JCN54WW released 06/15/2020). After several reboots the
network keeps disconnecting,
However the solution presented by Pablo "options rtw88_pci disable_aspm=1"
works with the ubuntu stock kernel
The problem persists in the tested 5.9 kernel (tried with cold boot and reboot).
Also, if I boot cycle through windows the wifi works.
I attached the dmesg.
** Attachment added: "Dmesg error with kernel 5.9"
Cold boot does not help.
WiFi has a very strange behavior:
If I cold boot the WiFi crashes after a random period of time.
Also, I've noticed that using torrent clients or accessing speed-test pages
like fast.com tend to trigger the error (might be high WiFi load )
If I reboot after a crash
I've tested the kernel with the same results.
What was even stranger was the fact that after rebooting back to 19.10 i
couldn't connect to the network anymore.
Only after i rebooted to windows and back to linux thw wifi worked.
I've atached the dmesg with the kernel
** Attachment added:
Ok, after a few hours the problem came back so bios upgrade is not a solution.
While searching for a possible solution I discovered that there are a number of
distributions inpacted by this bug (not all debian based) so it must be a
kernel bug.

Hello!
I did a quick search with the error from dmesg "failed to read DBI register,
addr=0x0719" and found this.

Then I updated the bios of my laptop to latest version available from Lenovo
website (I have dual boot) and now wifi
This was the tail of dmesg on the last crash
