September 13, 20232 yr Hello guys. I was recently notified by the Fix Common Problem plugin of Machine Check Events. Following its instructions, I then proceeded to check the syslog, in which I found the following error: Sep 12 21:18:46 Titanium-Server kernel: mce: [Hardware Error]: Machine check events logged Sep 12 21:18:46 Titanium-Server kernel: [Hardware Error]: Corrected error, no action required.
