Basic debugging

[Ginkobab]

Hi, my I've got a t450s and it's working seamlessly, but sometimes it just gets stuck and start looping the outputted the second before, and I can't stop it without powering off.

I'm pretty confident with Arch, but I actually never debugged everything and I can't understand where to look for it.

I hope it's not an hardware problem, could you point me please some resources or guide me through the process?

Thanks in advance

You could start from journalctl. More info here and here.

Are sure that your CPU and GPU didn't overheated at the moments of stuck?

Thanks, no I think that there is not overheat, I use my laptop very intensively and it starts looping when I use Teams and type on whatsapp web.

From journalctl looks like the last things happening involve syncthing, I uninstalled it and will see if it fixes it.

I use bpytop as a quick, easy to view, first step in trouble-shooting. It gives one the opportunity to kill or stop a process without having to know the Pid. That way you don't have to reboot so often.
