Ubuntu MATE crashed the other day while @jaymeb was just using the browser and then it started booting to initramfs prompt. I just booted into a USB live session involving fsck, lsblk, df, vgchange, mounting the boot drive and looking at syslog, and chrooting in. I can’t really see what is wrong. There were some PCI Bus Errors in the syslog. Also the end of syslog was several lines of just “&^” repeating.
