Some services take a long time to stop - I'm guessing clamav may be one of them. Not sure why you should then get a failed unmount of /var - that could be the first error. > When I boot up 1.290210] mce:[Hardware Error[: CPU 0: Machine Check: 0 > Bank 9: ae0000000036 > This looks like it might be a memory error to me: Bank 9 suggests that. https://en.wikipedia.org/wiki/Machine-check_exception explains MCE in more detail > 1,290283] mce: [Hardware Error]: TSC 0 ADDR 8d387240 MISC 7040000086 and > then > That also looks like a memory address > 1.290354] mce: [Hardware error]: Processor 0:906eb TIME 1688865217 Socket 0 > C O microcode f0 > Just reporting the error > > Also my system freezes, I thought it was just the mouse but it is the whole > system.
