Recently I saw the instructions from Ping-Ke Shih in this Ubuntu bug report=
:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927808
and realised I never powered off the laptop when I tested disable_aspm=3D1.
I always rebooted.

So I added again "options rtw88_pci disable_aspm=3D1" in a file in /etc/mod=
probe.d/
and powered off the laptop. It seems to work. It's been 11 days with no fre=
eze now.

Here is my information for dmidecode again:
