Fedora 34 sometimes shuts down without warning

Hi,
I got a somehow weird problem. Fedora 34 works like charm on my Dell xps 13 (9370). Only sometimes, without anything specific happening before, the machine shuts down and I have to login again. Those shotdowns normally appear around a minute after I started the machine. Am quite puzzled about this behaviour. Has anyone an idea, what might cause these shutdowns?

My immediate response would be that it’s perhaps overheating, and so the system shuts down to protect your hardware.

Can you look at your logs to see what they say? That should give us some idea of what’s causing the issue.

Hi Ankur, thanks for your immediate response.
I don’t think, that this can be caused by overheating, cause it normally occurs after freshly starting the machine. As soon as it happens another time, I will check the logs and post them here.
Best

Sure, but you can check logs from previous boots also where you should see something about this particular issue. That’s also documented in the quick-doc.

Is this after the system rebooted?

If it’s a kernel crash, there should be something in the logs. Can you check the log from the boot where this happened to see what it says? Screenshots from abrt don’t give us enough information, unless abrt also files a bug for you which it doesn’t seem to do here.

Do you remember if this happened after a recent update? You could then reboot into an older kernel to see if you still see the issue there.
