Bug Description

I have Lenovo ThinkPad X1 Carbon 7th (20QD003CRT), wifi adapter "Intel Corporation Cannon Point-LP CNVi [Wireless-AC] (rev 11)". Xubuntu 19.10 amd64 installed, without dualboot (no any other system installed). I use UEFI to boot.

Problem: yesterday my internal wifi adapter stopped to work for some seconds, GUI (XFCE desktop) freezed too, and then returned back to work.

All from /var/log/syslog for this time:

Again the same problem, with fresher software: Xubuntu 20.04, Kernel version 5.4.0-74-generic.
Laptop is different, but the same model:

No updates were installed recently (checked in /var/log/apt/history.log).
