Notebook started freezing since before last weekly update. It will stop responding for like one minute, then resumes and everything I clicked/tried to launch while it was frozen fires up at once. Then it works for a moment, and freezes again.
CPU usage remains low all the time, no abnormal hard disk activity either. The computer just seems to freeze while being idle.
Any ideas how can I start to tackle this issue? Thanks a lot!
I wouldn’t have actually replied if I didn’t see that you have the same CPU as I have (and same graphics card).
If it’s a recently fresh ISO install, it’s probably kernel 5.6. I’ve had the absolute same freeze problems, for minutes at a time, but on a fresh install - updating to kernel 5.7 and doing an auto driver update fixed the issue for me, at least for the moment.
Update. It seems the freezes were somehow connected to a corrupted Timeshift snapshot (btrfs) database. I got the first hint when I saw a message saying " failed to unmount /run/timeshift/backup" (or something close to that) when trying to reboot the notebook.
Upon the next boot I ran “sudo timeshift --check”, which deleted some incomplete snapshots. From that point onwards I have not had freezes anymore. Only an hour passed since though. Will keep observing.
