Hi there, hello. This seems to be my final update. About a week ago I returned to using Gajim, which, as I remember from earlier, also seemed to be responsible for these hangings, and they got more frequent (I haven't updated any software for the last 2 months). I decided to move to the kernel version 6.1.1, which I earlier marked as "good", and my laptop hung last evening during the shutdown. As always, nothing in the logs. I tried to compile some versions from 5.15.y branch, but either I had a bad luck, or the commits weren't properly compatible with GCC 12 yet, but they (.48 and .78) emitted warnings, so I never used them (or I broke the repo, who knows). Due to the fact that software does have impact on this behaviour, and due to my health issues and potential conscription (cuz our army doesn't care about health), which will cut me from my laptop for a long-long time, I give up on bisecting. I'll just update all my software (there's also a GCC upgrade in the repos) and hope for the best. Sorry for inconvenience and have a great day. Thank you very much.
