I've bought a new pc setup a couple of days ago and installed Ubuntu on the machine. When I play a certain video, it restarts after a while on VLC. Playing videos on YouTube doesn't cause this problem and playing other videos on VLC doesn't cause it either.

How can I troubleshoot this problem and see why the pc crashes and restarts ?

Additional info:

/proc/sys/kernel/panic; is set to 0

journalctl -x -p err results are:

Problem persists with live boot.

Processor: Ryzen 5 5600g, Ram: 16GB.
Ubuntu version: Ubuntu 20.04.4 LTS focal.

It could be that the power supply is undervolting, but I've set the CPU frequency to 80% and still restarts. Is there a way to troubleshoot the PSU?

  • Check logs journalctl -xe -b -k. Maybe a temperature issue? Did you try doing the same on a live boot? – Pablo Bianchi Jun 07 '22 at 21:39
  • Done thanks for clarifying the issue – Dev chimp Jun 08 '22 at 03:51

    Set logs to persist multiple boots and then check exactly when the PC crash, start using sudo journalctl -x (probably -p err will return less noise) – Pablo Bianchi Jun 08 '22 at 05:24

    I've updated with a complete log of what happens in between the reboots.. but it seems pretty normal to me. does it mean it's a hardware problem ? if that's the case is there steps to identify where the issue lies ? – Dev chimp Jun 09 '22 at 07:29
  • This strikes me as a potential vulnerability exploit. Can you create a virtual machine with Gnome Boxes and try running the video on there? If it crashes the VM when you do this, I'd save the video file on a flash drive, reinstall Ubuntu entirely to clean up any potential malware, and then proceed with further debugging steps to see if it affects the latest version of VLC in a VM. – ArrayBolt3 Jun 09 '22 at 07:39
  • Those errors don't seem related. Already check with lower -p? Computer is up-to-date? That certain video with a live boot on other PC doesn't crash? Add the output of relevant lines of mediainfo certainvideo – Pablo Bianchi Jun 09 '22 at 08:49
  • I have another laptob with ubuntu 22 loaded on it, it doesn't crash the laptob. I don't think it's not related to vlc program itself as the pc does the same crash when I'm browsing pinterest.com with multiple videos on the page. but I'm playing some courses for a while now and my pc is not crashing. and youtube is working just fine. – Dev chimp Jun 09 '22 at 13:07
  • I have tried lowering CPU power to 50%,also running fans at maximum speed, I even tried re installing ubuntu.. the problem is the same – Dev chimp Jun 09 '22 at 13:07
