I am new to finding logs about crashes and issues that I am running into. I am trying to diagnose why I get what seems to be a full system lockup when using Kodi. Between 3 - 60 min I will get a solid color screen, no response and keyboard, my SSH connection will lock up and I can't reconnect. I am not using a keyboard with lights so I am unsure if it is a kernel panic or where to start looking for what the issue is. I only get this when running Kodi, sometimes while not even playing a video. I have put some stress on the hardware to test it while compiling a few packages and everything is ok. I am up to date on all packages.
Linux 4.3.3-3-ARCH x86_64
Intel(R) Celeron(R) CPU N2930
One thing to try: Open a console and follow the journal log
$ journalctl -f
then start Kodi.
Or does Kodi have a debug switch if you run it from a console?
Enable debugging in kodi, see their wiki, and you might learn something when you reboot and inspect that log. I believe I saves the old log so you will not need to worry about overwrighting it upon rebooting.
