I have left my laptop in screen-locked state (Super+L) overnight, and recently noticed an increasing frequency of finding it hung in the morning. I'm pasting part of the log here. A longer version can be found here: https://pastebin.com/R75iX8wP
One can notice that everything seems to be fine until ~07:05:00. Then the system froze. I suspect it's because of the driver of my WiFi card but not sure. I'm on Ubuntu 20.04 LTS, Linux 5.4.0-39-generic x86_64, xps 7390 2-in-1. I'm new to the system log. I wonder how I can verify this or find the faulty process. Any input would be appreciated!
