Status in linux package in Ubuntu: Confirmed 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.
