A few days ago I run upgrade procedure (sudo apt update && sudo apt upgrade && sudo apt dist-upgrade). It seems that a new kernel was installed: 5.4.0-52-generic. After reboot my laptop hangs. I'm only able to run it using previous kernel: 5.4.0-51-generic.

How can I investigate what's went wrong with 5.4.0-52-generic kernel and fix it?

    The same: unbootable, kernel panic on inability to mount root FS - but I don't afford to reproduce now. – Netch Nov 01 '20 at 22:19
