Sometimes my GNOME shell (or even more than that?) stops responding, and the only option is a hard reboot with a button on my computer's casing. Neither any keyboard shortcuts, nor the mouse are working. The clock stops, which actually helps to notice the crash (if I was afk when it happens - which is quite often the case) and note down the time of it.
The logs stop writing by the time of the total freeze. For instance, today the clock stopped at 11:14. The last logs before the reboot were written at 11:10:

The occurrences of those freezes might correlate with the events related to updates, such as the system starts searching for them, downloading, or like now, it happens right after the installation. But it was never the case that some update made my system unusable: I reboot after this freeze and everything is back to normal.
The kernel logs were last written 10 minutes before the freeze:

So I know, this is not just my setup.
The freezes are luckily not very frequent and I can live with them, but of course one day I may loose some unsaved work...
