This started today and hasn’t happened before. Initially I thought it was an application from work that was causing issues. I SSHed into the machine and didn’t see anything strange - I used btop.
I updated the system and rebooted. A few minutes later when I got to the machine to check everything, was frozen again. I hadn’t even logged in.
I’ve used the eos-sendlog feature to get the logs and it seems like it might be GPU related.
I was using KDE with X11 when this happened, but I’ve been using that combination for months at this point. Nothing that I’m aware of has changed or been updated recently to possibly cause this issue.
Update: I’ve done a complete shutdown (turned the PSU off) and rebooted with the LTS kernel. So far so good. It doesn’t seem to be a hardware issue as it worked fine on the live USB.
You tried updating, but do you have snapshots set up to roll back to a time you’re sure it was working?
I’m 80% sure I do. I hadn’t updated for a few days (before today) and it had been working up until earlier today.
Still worth trying a known good os install. If not a snapshot from earlier, some live iso sessions.
If the problem persists even there, it’ll indicate that your hardward is bowing out.
I spent some time in a live ISO and had no issues. Haven’t tried a snapshot yet though.
Good sign.
