I have a repeating problem where my system just crashes and restarts for no apparent reason. The only system change I made recently was to move to the Noveau video driver. Of note, when the system restarts there is a message (during boot) which says there is a hardware error with CPU 9. The system does run for hours for example playing a game without any issue. I have attached the syslog link https://1drv.ms/u/s!Ag2UoFuJVGMmnBeA...Q86Fb?e=jjQ9rN , can anyone give me some insight into whether this is a video driver problem or a hardware issue please.
